Superconducting qubits with 1 second coherence time using rotation codes
Quantum computers use highly entangled qubits to achieve their exceptional computational power. However, the qubits also easily entangle with their environment, leading to errors. Future quantum computers can be protected against such errors by encoding each logical qubit redundantly in thousands of physical qubits. This daunting overhead can be reduced exponentially by improving the quality of the physical qubits. We can also replace the two-level physical qubits with cavities, which are described by continuous variables. This built-in redundancy can further reduce the overhead for fault-tolerant quantum computation. In this proposal, I aim to develop a qubit based on superconducting…
