Acceleration of Free Electrons by Photonic Time-Crystals
Lior Bar-Hillel, Alexey Gorlach, Ido Kaminer +1
We study the quantum interaction between free electrons and photons in a time-varying media, and find that periodic modulation exponentially amplifies electron-photon coupling with…
Generalized Conditional Displacement
Shiran Even-Haim, Asaf A. Diringer, Ron Ruimy +4
Conditional displacement with a qubit ancilla is a critical component in continuous-variable error correction protocols. We present the generalized conditional displacement operato…
Superluminal Correlations in Ensembles of Optical Phase Singularities
Tomer Bucher, Alexey Gorlach, Arthur Niedermayr +16
Phase singularities are universal features found across diverse wave systems. Their ensembles exhibit distance correlations governing exotic material phases. However, the full corr…
Supercoherence: Harnessing Long-Range Interactions to Preserve Collective Coherence in Disordered Systems
Alexey Gorlach, Andrea Pizzi, Klaus Mølmer +3
Artificial quantum systems with synthetic dimensions enable exploring novel quantum phenomena difficult to create in conventional materials. These synthetic degrees of freedom incr…
Spin Squeezing in Electron Microscopy
Shiran Even-Haim, Ethan Nussinson, Roni Ben-Maimon +5
Quantum metrology experiments in atomic physics and quantum optics have demonstrated measurement accuracy beyond the shot-noise limit via multi-particle entanglement. At the same t…
Two-electron quantum walks can probe entanglement and decoherence in an electron microscope
Offek Tziperman, David Nabben, Ron Ruimy +8
Classical physics is often a good approximation for quantum systems composed of many interacting particles, although wavepacket dispersion and scattering processes continuously ind…
