Better info transfer marks step forward for quantum computing

Quantum computers, on the other hand, are based on quantum bits, also known as qubits, which can be made from a single electron. Unlike ordinary transistors, which can be either “0” (off) or “1” (on), qubits can be both “0” and “1” at the same time. Just like ordinary computers, however, quantum computers need a way to transfer quantum information between distant qubits—and that presents a major experimental challenge. Exploiting a strange state of matter In a second paper, the researchers demonstrated another technique of transferring information between qubits, using an exotic state of matter called time crystals. As a result, AQT has the potential to improve the transfer of information between qubits, which is essential for quantum networking and error correction. The ability of individual qubits to occupy these so-called superposition states, where they are in multiple states simultaneously, underlies the great potential of quantum computers. Unlike most methods of transferring information between qubits, which rely on carefully tuned electric or magnetic-field pulses, AQT isn’t as affected by pulse errors and noise.
