Scientists used antimony atoms to improve quantum computing by making qubits more stable, like a quantum cat, and ...

A qubit can be any quantum object with two or ... a quantum mechanical mixture of one and zero—a condition known as "superposition." This versatility builds the framework for the awesome ...

Whereas a classical bit is either a 0 or 1, a quantum computing bit (the "qubit") can be both a 0 and a 1 or any value in between at the same time. Meaning "many possibilities," superposition ...

Errors in quantum computers are an obstacle for their widespread use. But a team of scientists say that, by using an antimony ...

Scientists trapped ultra-cold molecules, improving quantum computing with better stability, accuracy, and computational possibilities.

Like its doomed namesake, the cat qubit exists in a double superposition of two quantum states simultaneously. More conventional qubits exist in a single superposition, existing as both 0 and 1.

The superposition would have been writ large ... The key building block of a basic quantum computer is the so-called qubit. These are analogous to the regular bits in a conventional computer ...

The Swiss startup has found a way to allow qubits to move in all spatial directions like an aeroplane, instead of like cars ...

For example, virtual qubits can exist as a superposition of 0 and 1. Similarly, superconducting qubit, which is a physical electronic device, also has lower and higher energy states represented by ...

because the algorithms exploit the magic (superposition and entanglement) of quantum computers. The difficulty in designing quantum computers has to do with errors. The qubit interactions cause ...
