The promise of so-called “quantum advantage” is simple. By harnessing the counterintuitive rules of quantum mechanics, quantum computers should be able to—in theory—surpass the computational potential ...

A spin qubit, in which quantum information is encoded in the spin state of an electron, is one of the most promising platforms for quantum computing. Spin qubits exhibit long coherence times and are ...

For the first time, physicists at CERN have coaxed an antiproton — a mirror twin of the matter that makes up our world — into behaving like a quantum bit, or qubit. The antiproton held its quantum ...

A cryostat from a quantum computer stands during a press tour of the Leibniz Computing Center in 2022. Qubit is a key term in one of the most buzzy areas of technology: quantum computing. Qubits are ...

Researchers from the U.S. Department of Energy's (DOE) Brookhaven National Laboratory and DOE's Pacific Northwest National Laboratory (PNNL) have uncovered an unexpected interface layer that may be ...

In a major step toward practical quantum computers, Princeton engineers have built a superconducting qubit that lasts three times longer than today’s best versions. “The real challenge, the thing that ...

Holes in silicon quantum dots are promising for spin qubit applications due to the strong intrinsic spin-orbit coupling. The spin-orbit coupling produces complex hole-spin dynamics, providing ...

Qubits, or quantum bits, are the fundamental units of information in quantum computing. Unlike classical bits, which can only exist in one of two states (0 or 1), qubits can exist in multiple states ...

Built with the help of AI agents, Microsoft's Majorana 2 takes a different approach to quantum computing, focusing on hardware-level stability as rivals like Google push scaling and error correction ...

Microsoft's Majorana 2 in 2026 is 1,000 times more reliable than its predecessor, thanks to AI. Here is why the 2029 goal for quantum computers is now reachable.

Today, a startup called Atom Computing announced that it has been doing internal testing of a 1,180 qubit quantum computer and will be making it available to customers next year. The system represents ...
