NVIDIA has unveiled what it describes as the world’s first open-source family of quantum artificial intelligence (AI) models, called NVIDIA Ising, aimed at accelerating the development of scalable and reliable quantum computing systems.

The new models are designed to help researchers and enterprises tackle two of the biggest challenges in quantum computing—processor calibration and quantum error correction—both critical to enabling real-world applications at scale.

NVIDIA said the Ising family provides high-performance, scalable AI tools that can improve the reliability of quantum processors, enabling hybrid quantum-classical systems to handle more complex workloads.

Jensen Huang, founder and chief executive officer of NVIDIA, said: “AI is essential to making quantum computing practical. With Ising, AI becomes the control plane — the operating system of quantum machines — transforming fragile qubits to scalable and reliable quantum-GPU systems.”

The company added that its models deliver up to 2.5 times faster performance and three times higher accuracy in decoding processes required for quantum error correction.

Addressing key engineering bottlenecks

The Ising platform includes specialised models for calibration and decoding:

Ising Calibration: A vision-language model that is significantly smaller than alternatives and can rapidly interpret quantum processor measurements to automate calibration
Ising Decoding: Two variants of a 3D convolutional neural network model optimised for either speed or accuracy, enabling real-time quantum error correction

These capabilities are intended to improve system stability and enable larger-scale quantum computations.

A range of global enterprises, academic institutions and research labs have already begun adopting the Ising models for quantum development. These include organisations such as Atom Computing, Harvard John A. Paulson School of Engineering and Applied Sciences, Fermi National Accelerator Laboratory, and Lawrence Berkeley National Laboratory, among others.

The models are also being deployed by universities including Cornell University, University of California San Diego and University of Chicago.

Supporting broader quantum ecosystem

NVIDIA is also offering supporting tools, including quantum computing workflows, training data and NVIDIA NIM microservices, enabling developers to fine-tune models for specific hardware architectures.

The Ising models integrate with NVIDIA’s broader quantum stack, including CUDA-Q software and NVQLink hardware interconnects, providing a full ecosystem for hybrid quantum-classical computing.

The global quantum computing market is expected to exceed $11bn by 2030, according to Resonance, with progress in error correction and scalability seen as key to unlocking commercial applications.

NVIDIA said the open-source nature of the Ising models will allow developers to retain full control over data and infrastructure, while accelerating innovation across the quantum computing landscape.

US shuts down Iran’s maritime trade despite optimism for more talks

Officials from Pakistan, Iran and the Gulf also said negotiating teams from the US and Iran could return to Pakistan later this week, although one senior Iranian source said no date had been set

US shuts down Iran’s maritime trade despite optimism for more talks

TT

The US said on Wednesday its military had completely halted trade going in and out of Iran by sea, even though President Donald Trump said talks with Tehran on ending the war could resume this week.

Trump said negotiations between US and Iranian officials could resume in Pakistan in the next two days and Vice President JD Vance, who led weekend talks that ended without a breakthrough, said he felt positive about where things stood.

“I think you’re going to be watching an amazing two days ahead,” Trump told ABC News reporter Jonathan Karl, adding he did not think it would be necessary to extend a two-week ceasefire that ends on April 21.

“It could end either way, but I think a deal is preferable because then they can rebuild,” Trump said, according to a post by Karl on X.

“They really do have a different regime now. No matter what, we took out the radicals.”

Officials from Pakistan, Iran and the Gulf also said negotiating teams from the US and Iran could return to Pakistan later this week, although one senior Iranian source said no date had been set.

Despite the optimistic note, more vessels were being turned back under the US blockade on Iranian ports, including a US-sanctioned and Chinese-owned tanker Rich Starry that was making its way back to the Strait of Hormuz on Wednesday after exiting the Persian Gulf.

Admiral Brad Cooper, the head of the US Central Command, said American forces had completely halted economic trade going in and out of Iran by sea, which he said fuels 90 per cent of Iran’s economy.

“In less than 36 hours since the blockade was implemented, US forces have completely halted economic trade going into and out of Iran by sea,” Cooper said in a post on X.

Earlier the US military said it had intercepted eight Iran-linked oil tankers since the start of the blockade on Monday, according to the Wall Street Journal.

Return to Islamabad

Trump, speaking to the New York Post on Tuesday, said his negotiators are likely to be back, thanks largely to the “great job” Pakistan’s army chief, Field Marshal Asim Munir, was doing to moderate the talks.

Later on Tuesday, at an event in Georgia, US Vice President JD Vance said Trump wanted to make a “grand bargain” with Iran but there was a lot of mistrust between the two countries.

“You are not going to solve that problem overnight,” he said.

The signs of diplomatic engagement to end the conflict that began on February 28 helped calm oil markets, pressing benchmark prices down for a second day on Wednesday. Asian stocks rose while the safe-haven dollar stabilised after falling for a seventh straight session overnight.

The war has prompted Iran to effectively shut the Strait of Hormuz, a crucial global waterway for crude and gas transport and cut shipments from the Gulf to global buyers, particularly in Asia and Europe.

About 5,000 people have died in the hostilities, including about 3,000 in Iran and 2,000 in Lebanon.

Sticking points

Iran’s nuclear ambitions were a key sticking point at the weekend talks. The US had proposed a 20-year suspension of all nuclear activity by Iran, while Tehran had suggested a halt of three to five years, according to people familiar with the proposals.

Speaking in Seoul, the head of the International Atomic Energy Agency (IAEA), Rafael Grossi, said the length of any moratorium on Iranian uranium enrichment was a political decision and it was possible Tehran might accept a compromise as a confidence-building act.

The US has also pressed for any enriched nuclear material to be removed from Iran, while Tehran has demanded that international sanctions against it be removed.

One source involved in the negotiations in Pakistan said back-channel talks since the weekend had produced progress in closing that gap, bringing the two sides closer to a deal that could be put forward at a new round of talks.

However, in a major complication for peace prospects, Israel has continued to attack Lebanon as it targets Hezbollah, an Iran-backed militant group. Israel and the U.S. say that campaign is not covered by the ceasefire, while Iran insists it is.

On Tuesday, the UK, Canada, Japan and seven other countries condemned the killings of UN peacekeepers in Lebanon and called for “an urgent end to hostilities”.

The statement comes after the deaths of three Indonesian peacekeepers last month. The countries welcomed the ceasefire agreed between the US, Israel and Iran.

Article Summary
Sharjah's nurseries will gradually reopen from April 16th, prioritising government and commercial building locations. The Sharjah Private Education Authority (SPEA) is mandating emergency protocol training for staff, who return to campuses beforehand to prepare. This phased return, aligned with UAE guidance and similar actions in Dubai, ensures a safe environment for children following disruptions.

Sharjah will begin a phased return to in-person early childhood education from April 16, as authorities move to restore on-site learning following weeks of disruption.

The Sharjah Private Education Authority (SPEA) said late on Tuesday that nurseries located in government facilities and commercial buildings will reopen to children from Thursday, subject to the completion of mandatory staff training on emergency and crisis protocols.

Administrative and teaching staff across private schools and nurseries in Sharjah have already been instructed to return to campuses from Wednesday, April 15, according to reports. The authority said the early return is aimed at ensuring institutions are fully prepared, including the rollout of training programmes designed to strengthen emergency response capabilities.

“This is subject to the completion of training for nursery administrative and teaching staff on emergency and crisis protocols, to ensure the children return to a safe and supportive environment,” SPEA said.

The decision follows guidance from the Education, Human Development and Community Development Council, which earlier confirmed that nurseries across the UAE would reopen in phases.

Sharjah’s move aligns with similar steps in Dubai, where the Knowledge and Human Development Authority (KHDA) has also confirmed a gradual return for early childhood centres from April 16.

ClearTax said on Tuesday it had been approved as an ‘Accredited Service Provider’ under the UAE’s e-invoicing framework, as companies step up preparations ahead of a July deadline to appoint certified providers.

The accreditation, granted under the UAE Ministry of Finance and Federal Tax Authority framework, comes as businesses move to comply with new requirements that will standardise digital invoicing and reporting.

The shift is expected to push companies to upgrade tax and finance systems, with governments globally increasingly using e-invoicing data and analytics to monitor transactions and automate compliance processes.

ClearTax has supported e-invoicing, tax compliance mandates across multiple markets

ClearTax said its offering draws on experience supporting e-invoicing and tax compliance mandates across multiple markets, including India, Saudi Arabia, Malaysia and Europe.

The company has previously worked on India’s 2020 e-invoicing rollout, advised on Saudi Arabia’s ZATCA Phase I and II implementation, and operates within Malaysia’s framework as an accredited provider, as well as Europe’s Peppol-based network.

“Most enterprises today are still trying to solve tax operations through ERP connectors, manual efforts and spreadsheets,” said Archit Gupta. “As governments move toward real-time visibility and AI-driven scrutiny, that approach starts to break down.”

He added that companies need to shift from reactive compliance to what he described as continuous, data-driven tax processes.

The company said it has committed $50m to expand its operations in the UAE, including building local teams and infrastructure to meet data residency requirements.

ClearTax said it is already working with enterprises in sectors including real estate, manufacturing, banking, financial services and insurance, as well as retail and consumer goods.

The UAE’s e-invoicing rollout is part of broader efforts to modernise tax administration and improve transparency, with companies expected to integrate accredited providers into their systems ahead of the July deadline.
