Huge congratulations to our CDT cohort 9 student Chris Corlett for his published paper "Speeding up quantum measurement using space-time trade-off"

We present a scheme for speeding up quantum measurement by entangling the target system with ancillary systems. In the idealised situation of perfect entangling operations and no decoherence, the scheme gives an exact space-time trade-off meaning the readout time reduces linearly with the number of ancilla. We verify this scheme is robust against experimental imperfections through numerical modelling of gate noise and readout errors. This hardware-agnostic approach is broadly applicable to a range of quantum technology platforms and offers a route to accelerate mid-circuit measurement as required for effective quantum error correction.
