While conventional computers store information in the form of bits, fundamental pieces of logic that take a value of either 0 or 1, quantum computers are based on qubits. These can have a state that ...

Scientists and engineers have been toiling on quantum computing systems for decades with only limited success. While the hardware has become much more capable, there are still some fundamental ...

Researchers have produced, stored, and retrieved quantum information for the first time, a critical step in quantum networking. The ability to share quantum information is crucial for developing ...
