Quantum computers will need large numbers of qubits to tackle challenging problems in physics, chemistry, and beyond. Unlike classical bits, qubits can exist in two states at once—a phenomenon called ...

Quantum computers hold great promise for exciting applications in the future, but for now they keep presenting physicists and ...

A quantum bit, otherwise known as a qubit, is the basic unit of data in quantum computing. Like a binary bit in classical computers, as it can store information, but behaves very differently thanks to ...

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 ...
