Environment-Assisted Generation of Non-Gaussian Wavepacket Quantum States
Maryam Khanahmadi, Klaus Mølmer
Generating non-Gaussian states and converting them into traveling wavepackets is crucial yet challenging for scalable, fault-tolerant quantum computing. We present a hardware-effic…
Theoretical framework for enhancing or enabling cooling of a mechanical resonator via the anti-Stokes or Stokes interaction and zero-photon detection
Jack Clarke, Evan A. Cryer-Jenkins, Arjun Gupta +11
We develop a theoretical framework to describe how zero-photon detection may be utilized to enhance laser cooling via the anti-Stokes interaction and, somewhat surprisingly, enable…
Enhanced Laser Cooling of a Mechanical Resonator via Zero-Photon Detection
Evan A. Cryer-Jenkins, Kyle D. Major, Jack Clarke +11
Throughout quantum science and technology, measurement is used as a powerful resource for nonlinear operations and quantum state engineering. In particular, single-photon detection…
Probing Hilbert Space Fragmentation with Strongly Interacting Rydberg Atoms
Fan Yang, Hadi Yarloo, Hua-Chen Zhang +2
Hilbert space fragmentation provides a mechanism to break ergodicity in closed many-body systems. Here, we propose a feasible scheme to explore this exotic paradigm on a Rydberg qu…
Boundary Time Crystals Induced by Local Dissipation and Long-Range Interactions
Zhuqing Wang, Ruochen Gao, Xiaoling Wu +4
Driven-dissipative many-body system supports nontrivial quantum phases absent in equilibrium. As a prominent example, the interplay between coherent driving and collective dissipat…
Subtraction and Addition of Propagating Photons by Two-Level Emitters
Mads M. Lund, Fan Yang, Victor Rueskov Christiansen +2
Coherent manipulation of quantum states of light is key to photonic quantum information processing. In this Letter, we show that a passive two-level nonlinearity suffices to implem…
