Light pulses can be stored and retrieved in the glass cell, which is filled with rubidium atoms and is only a few millimeters in size. Credit: © University of Basel, Department of Physics/ScixelResearchers at the University of Basel have built a quantum memory element based on atoms in a tiny glass cell. In the future, such quantum memories could be mass-produced on a wafer.It is hard to imagine our lives without networks such as the internet or mobile phone networks. In the future, similar networks are planned for…

In the BLG double quantum dot used in this work, electrons (the blue spheres) have both an intrinsic angular momentum (spin, given by the arrows through the spheres) and a pseudo-​spin (valley, given by the rings rotating in opposite directions). Credit: ETH Zurich/Chuyao Tong Researchers in the Laboratory for Solid State Physics at ETH Zurich found evidence that bilayer graphene quantum dots may host a promising new type of quantum bit based on so-​called valley states.In quantum computing, the question as to what…

Governments and businesses are not prepared for the havoc quantum computers will sow in cybersecurity by the end of the decade, according to an International Business Machines Corp. executive.  “Is quantum going to really create a cybersecurity Armageddon?” Ana Paula Assis, IBM's general manager of Europe, Middle East and Africa, said on a panel at the World Economic Forum in Davos on Wednesday. “It's going to.” Quantum computers, an emerging technology that vastly accelerates processing power by performing calculations…

The government is likely to allot up to Rs 10,000 crore for setting up supercomputing and quantum computing hubs in collaboration with the private industry under public-private partnerships, officials aware of the development told ET.An announcement to this effect is likely to be made during Global Artificial Intelligence Summit and Awards scheduled to be held here on January 18 and 19, a government official said.Elevate Your Tech Prowess with High-Value Skill CoursesOffering CollegeCourseWebsiteIndian School of…

A research team has developed a machine learning model to address variability in quantum devices caused by material imperfections. By analyzing electron flow, the team inferred internal disorder patterns, improving predictions of quantum device performance and guiding material optimization. Credit: SciTechDaily.comA study led by the University of Oxford has used the power of machine learning to overcome a key challenge affecting quantum devices. For the first time, the findings reveal a way to close the ‘reality gap’: the…

A breakthrough study has shown that qubits, the fundamental units of quantum computers, can achieve long lifetimes even in dense environments. This contradicts the earlier belief that qubits need to be isolated in ultra-pure materials, revealing a new approach where rare-earth ion pairs form highly coherent qubits.

Recent studies challenge the quantum Cheshire cat effect’s initial interpretation, highlighting the role of contextuality in quantum mechanics. This research suggests that the perceived separation of particles and their properties is a result of how quantum systems are measured, not an actual physical phenomenon. Understanding this could unlock new insights into quantum mechanics and its applications.

Microsoft Corp. is using powerful computers and artificial intelligence to help researchers speed up the painstaking work required to discover new chemical compounds and materials that could be used for everything from batteries to eco-friendly paints.The Pacific Northwest National Laboratory used the company's Azure Quantum Elements service to quickly assess 32 million potential materials for a new battery, according to Jason Zander, Microsoft's executive vice president for strategic missions and technologies. The…

Recently, Microsoft built a clock.Well, “built” may be overstating things. Members of the company’s quantum computing team found a small digital clock in a wood case on Amazon—the kind you might mistake for a nicer-than-usual trade show tchotchke. They hacked it to run off two experimental batteries they’d created in collaboration with staffers at the U.S. Department of Energy’s Pacific Northwest National Laboratory (PNNL). Then they dressed up its enclosure by adding the logo of Azure Quantum Elements, the Microsoft…
