The Sacrificial Qubit
The U.S. and Australian Multidisciplinary University Research Initiatives (MURI and AUSMURI, respectively) have provided funding to universities to study potential benefits of spectator qubits — qubits functioning as a calibration sensor while primary qubits perform processing. The “sacrificial qubits” will permit real-time calibration in the quantum computing device thus enhancing overall system efficiency. April 19, 2018.
