Alice & Bob Tapes Out New Chip with Error Correction in Quest to Achieve a 0.0001% Logical Qubit Error Rate

The chip is codenamed Helium 1 and contains 16 qubits to test out Alice & Bob’s cat qubit architecture for achieving a very high fidelity logical qubit. The term “tape out” means that the company has finished the design and sent the design files to a fabrication facility for construction. After the chip has been […]
