Dynamical decoupling of a quantum dot spin in a micropillar cavity for spin-multiphoton entanglement
H. Huet, P. R. Ramesh, R. Frantzeskakis +12
Graph states of mutually entangled photons are key resources for quantum computation and communication and can be generated by leveraging the entanglement between a single resident…

Hilbert Space Fragmentation and Subspace Scar Time-Crystallinity in Driven Homogeneous Central-Spin Models
Abhishek Kumar, Rafail Frantzeskakis, Edwin Barnes
We study the stroboscopic non-equilibrium quantum dynamics of periodically kicked Hamiltonians involving homogeneous central-spin interactions. The system exhibits a strong fragmen…

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…
