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 ...

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 ...

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 ...

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 ...

To achieve remarkable performances, quantum computing systems based on multiple qubits must attain high-fidelity entanglement between their underlying qubits. Past studies have shown that solid-state ...

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 ...

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 ...

Quantum computers aren’t just physics experiments tucked away in university basements anymore. They’re becoming real engineering projects, deployed by companies that care as much about wiring and ...

Quantum computing has been plagued with problems relating to reliability since the inception of the technology. The quantum bits, or qubits, used by quantum computers have a reputation for being ...
