Qubit That Lasts 3 Times As Long As The Record Is Major Step Toward Practical Quantum Computers

Researchers at Princeton University have reported a new quantum computing breakthrough. They developed a quantum bit, or qubit – the fundamental processing unit of quantum computers – that can last for over 1 millisecond. This is three times longer than the best-ever qubit lifetime in a lab setting and almost 15 times longer than what’s found in large-scale processors in industry, a major step forward.

Regular computer bits can take two states: 0 or 1. By using many of them, it is possible to conduct all the operations that computers do. The advantage of qubits , and our interest in them, is that they are not just 1s or 0s like the regular bit, but a superposition of those two states. T
