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 ...
The operation of quantum computers, systems that process information leveraging quantum mechanical effects, relies on the implementation of quantum logic gates. These are essentially operations that ...
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 ...
High-fidelity single 1,2,3,4,5 and two-qubit gates 5,6,7,8 have been demonstrated in semiconductor spin qubit platforms, motivating efforts towards large-scale quantum computing. Indeed, recent ...
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 ...

Physicists Make First Qubit out of Antimatter and It Could One Day Explain Why the Universe Exists At All
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 ...
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 ...
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 ...
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.
Everyone in quantum computing agrees that error correction will be the key to doing a broad range of useful calculations. But early every company in the field seems ...
