Sequential state preparation and measurement of multiple qubits via a single channel

Accurate state preparation and measurement (SPAM) is vital for performing high-fidelity quantum computation 1–3 . However, systems typically use individual readout hardware for each qubit, presenting a significant overhead to the scale-up of quantum computers 2,4 . In response, f...

Quantum spectroscopy with undetected photons for biomolecular sensing in the mid-infrared

We investigate numerical modelling of quantum spectroscopy with undetected photons for protein detection in the mid-infrared spectral region. Classical Fourier-transform infrared spectroscopy of protein samples (bovine serum albumin and N-terminal pro-brain natriuretic peptide) i...
