ADAPT-QAOA with a classically inspired initial state
Vishvesha K. Sridhar, Yanzhu Chen, Bryan Gard +2
Quantum computing may provide advantage in solving classical optimization problems. One promising algorithm is the quantum approximate optimization algorithm (QAOA). There have bee…
Protocol for nearly deterministic parity projection on two photonic qubits
Chenxu Liu, Rafail Frantzeskakis, Sophia E. Economou +1
Photonic parity projection plays a significant role in photonic quantum information processing. Non-destructive parity projections normally require high-fidelity Controlled-Z gates…
Long-distance photon-mediated and short-distance entangling gates in three-qubit quantum dot spin systems
Nooshin M. Estakhri, Ada Warren, Sophia E. Economou +1
Superconducting microwave resonator couplers will likely become an essential component in modular semiconductor quantum dot (QD) spin qubit processors, as they help alleviate cross…
How to really measure operator gradients in ADAPT-VQE
Panagiotis G. Anastasiou, Nicholas J. Mayhall, Edwin Barnes +1
ADAPT-VQE is a leading variational quantum algorithm as it circumvents the choice-of-ansatz conundrum by iteratively growing compact and arbitrarily accurate problem-tailored ansät…
Time-crystalline behavior in central-spin models with Heisenberg interactions
Rafail Frantzeskakis, John Van Dyke, Leon Zaporski +5
Time-crystalline behavior has been predicted and observed in quantum central-spin systems with periodic driving and Ising interactions. Here, we theoretically show that it can also…
Linear optical logical Bell state measurements with optimal loss-tolerance threshold
Paul Hilaire, Yaron Castor, Edwin Barnes +2
Quantum threshold theorems impose hard limits on the hardware capabilities to process quantum information. We derive tight and fundamental upper bounds to loss-tolerance thresholds…
