n the rapidly evolving field of quantum computing, silicon spin qubits are emerging as a leading candidate for building scalable, fault-tolerant quantum computers.
A new review titled "Single-Electron Spin Qubits in Silicon for Quantum," published in Intelligent Computing, highlights the latest advances, challenges and future prospects of silicon spin qubits for quantum computing.
Silicon spin qubits are compatible with existing semiconductor industry manufacturing processes, making them promising for universal quantum computers. They have several remarkable properties.
"They can have long coherence times, up to 0.5 seconds, single-qubit gate fidelities exceeding 99.95%, and two-qubit gate fidelities surpassing the fault-tolerant threshold," according to the authors.
In addition, silicon spin qubits can operate as "hot qubits" at temperatures of 1 Kelvin or above, and recent studies have even demonstrated gate fidelities required for fault-tolerant operations at this temperature.
