EurekAlert  February 18, 2021 The application of active error correction in a quantum computer is very complex and comes with an extensive use of hardware. An international team of researchers (Germany, Switzerland, the Netherlands) has proposed a design for a circuit with passive error correction. The circuit is designed in such a way that it is already inherently protected against environmental noise while still controllable. The concept thus bypasses the need for active stabilization in a highly hardware-efficient manner and would therefore be a promising candidate for a future large-scale quantum processor that has many qubits. By implementing a gyrator […]
