Variance minimisation on a quantum computer for nuclear structure
Isaac Hobday, Paul Stevenson, J. Benstead·Sep 16, 2022
Quantum computing opens up new possibilities for the simulation of many-body nuclear systems. As the number of particles in a many-body system increases, the size of the space if the associated Hamiltonian increases exponentially. This presents a cha...
Predicting molecular vibronic spectra using time-domain analog quantum simulation
R. MacDonell, T. Navickas, Tim F. Wohlers-Reichel +8 more·Sep 14, 2022
Spectroscopy is one of the most accurate probes of the molecular world. However, predicting molecular spectra accurately is computationally difficult because of the presence of entanglement between electronic and nuclear degrees of freedom. Although ...
Automated design of quantum-optical experiments for device-independent quantum key distribution
Xavier Valcarce, P. Sekatski, É. Gouzien +2 more·Sep 14, 2022
Device-independent quantum key distribution (DIQKD) reduces the vulnerability to side-channel attacks of standard QKD protocols by removing the need for characterized quantum devices. The higher security guarantees come however, at the price of a cha...
