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…
How Much Entanglement Do Quantum Optimization Algorithms Require?
Yanzhu Chen, Linghua Zhu, Chenxu Liu +3
Many classical optimization problems can be mapped to finding the ground states of diagonal Ising Hamiltonians, for which variational quantum algorithms such as the Quantum Approxi…
Minimizing state preparation times in pulse-level variational molecular simulations
Ayush Asthana, Chenxu Liu, Oinam Romesh Meitei +3
Quantum simulation on NISQ devices is severely limited by short coherence times. A variational pulse-shaping algorithm known as ctrl-VQE was recently proposed to address this issue…
Extracting perfect GHZ states from imperfect weighted graph states via entanglement concentration
Rafail Frantzeskakis, Chenxu Liu, Zahra Raissi +2
Photonic GHZ states serve as the central resource for a number of important applications in quantum information science, including secret sharing, sensing, and fusion-based quantum…
Proposal for generating complex microwave graph states using superconducting circuits
Chenxu Liu, Edwin Barnes, Sophia Economou
Microwave photonic graph states provide a promising approach for robust quantum communication between remote superconducting chips using microwave photons. Recently, Besse et al. […
