Reducing entanglement with a Hamiltonian derived Clifford transformation
James Brown, Erika Lloyd, Alexandre Fleury +2
Recently (Physica Scripta, 100(10):105401, 2025), an algorithm was introduced that deterministically generates a Clifford transformation from the Qubit Coupled Cluster (QCC) algori…
Offline recovery of magic and entanglement from noisy Pauli product states
Erika Lloyd, Alexandre Fleury, Marc P. Coons +2
The dependence of quantum algorithms on state fidelity is difficult to characterize analytically and is best explored experimentally as hardware scales and noisy simulations become…
Iterative Qubit Coupled Cluster using only Clifford circuits
James Brown, Marc P. Coons, Erika Lloyd +4
The performance of quantum algorithms for ground-state energy estimation is directly impacted by the quality of the initial state, where quality is traditionally defined in terms o…
Non-unitary Coupled Cluster Enabled by Mid-circuit Measurements on Quantum Computers
Alexandre Fleury, James Brown, Erika Lloyd +2
Many quantum algorithms rely on a quality initial state for optimal performance. Preparing an initial state for specific applications can considerably reduce the cost of probabilis…
