IBM’s quantum computers like Condor and Heron must be kept in an elaborate device called Quantum System Two which keeps them extremely cold Ryan Lavine for IBM Today, IBM unveiled two new quantum computers. The bigger of the two, dubbed Condor, is the second ever to have a total number …

The vacuum is not as empty as it might appear ElessarDesign/Shutterstock We may be able to harvest the quantum property of entanglement from apparently empty space, according to a group of researchers. If their proposal can be realised, it has the potential to reveal new information about the fundamentally quantum …

The quantum realm is full of strange effects, but there’s a reason why everything looks normal from our point of view, writes physicist Sebastian Deffner Source link

In the quantum world, cause doesn’t always come before effect Shutterstock / YanaBu Quantum batteries could charge more efficiently by skirting conventional rules of causality. Yuanbo Chen at the University of Tokyo and his colleagues analysed whether a particularly counterintuitive quantum phenomenon could play a role in powering quantum batteries …

A flywheel can makes an engine more useful BELL KA PANG/Shutterstock Two charged atoms could be used to build a quantum engine and store the energy it produces in a quantum version of a flywheel. Engines are designed to generate mechanical energy, or “work”. But they only do so in …

Monika Schleier-Smith is hoping to create space-time from scratch in her lab Harrison Truong/Stanford University SPACE-TIME may not be fundamental. Instead, according to the holographic principle, it emerges from something deeper, like a 3D hologram emerges from a flat surface. The principle says that space-time, and by extension gravity, arises …

IF YOU could empty the universe, what would be left over? The underlying structure of the cosmos is called space-time, and it is often likened to a fabric. But “space-time fabric is a science-fiction term”, says Jonathan Oppenheim, a physicist at University College London. There is no consensus about what …

The largest quantum computer yet built, created by Atom Computing Atom Computing The world’s first quantum computer to exceed 1000 qubits has more than double that of the previous record holder, IBM’s Osprey machine, which has 433 qubits. Though having more qubits doesn’t necessarily mean better performance, large numbers of …

MosaiQ’s generated images (bottom row) on a quantum computer look similar to items in the initial data (top row) and seem better than those made by other quantum methods (other rows) Daniel Silver et al. 2023 Artificial intelligence running on a quantum computer can now generate recognisable images of things …

Artist’s impression of quantum entanglement between two top quarks CERN The Large Hadron Collider (LHC) is best known for smashing particles together at high speed, but now this huge machine has been used for a more delicate experiment – investigating quantum entanglement. The results, demonstrating entanglement between two subatomic particles …
