Alice & Bob Tapes Out New Chip with Error Correction in Quest to Achieve a 0.0001% Logical Qubit Error Rate
Doug Finke2024-08-27T21:51:27-07:00The 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 built, it will undergo extensive testing, characterization, and calibration by the company's engineering team to realize the optimum performance and then made available for external use by the company's customers. Any lessons learned during this process will be utilized in the design of the next chip [...]
