Measuring distances in Hilbert space by many-particle interference
Karol Bartkiewicz, Vojtěch Trávníček, Karel Lemr
The measures of distances between points in a Hilbert space are one of the basic theoretical concepts used to characterize properties of a quantum system with respect to some etalo…
Genuine multipartite indistinguishability and its detection via generalized Hong-Ou-Mandel effect
Marcin Karczewski, Robert Pisarczyk, Paweł Kurzyński
The question whether two indistinguishable particles are bosons or fermions can be answered by observing the Hong-Ou-Mandel effect on a beam splitter. However, already for three pa…
Genuine monogamy relations in no-signaling theories - a geometric approach
Junghee Ryu, Daemin Lee, Jinhyoung Lee +2
Quantum correlations are subject to certain distribution rules represented by so-called monogamy relations. Derivation of monogamy relations for multipartite systems is a non-trivi…
Ideal Quantum Nondemolition Readout of a Flux Qubit Without Purcell Limitations
Xin Wang, Adam Miranowicz, Franco Nori
Dispersive coupling based on the Rabi model with large detuning is widely used for quantum nondemolition (QND) qubit readout in quantum computation. However, the measurement speed…
Resource-efficient analyzer of Bell and Greenberger-Horne-Zeilinger states of multiphoton systems
Tao Li, Adam Miranowicz, Keyu Xia +1
We propose a resource-efficient error-rejecting entangled-state analyzer for polarization-encoded multiphoton systems. Our analyzer is based on two single-photon quantum-nondemolit…
On dynamical stability of composite quantum particles: when entanglement is enough and when interaction is needed
Zakarya Lasmar, Adam S. Sajna, Su-Yong Lee +1
We consider an evolution of two elementary quantum particles and ask the question: under what conditions such a system behaves as a single object? It is obvious that if the attract…
Nonreciprocal Photon Blockade
Ran Huang, Adam Miranowicz, Jie-Qiao Liao +2
We propose how to create and manipulate one-way nonclassical light via photon blockade in rotating nonlinear devices. We refer to this effect as nonreciprocal photon blockade (PB).…
Proposal to Test Quantum Wave-Particle Superposition on Massive Mechanical Resonators
Wei Qin, Adam Miranowicz, Guilu Long +2
We present and analyze a proposal for a macroscopic quantum delayed-choice experiment with massive mechanical resonators. In our approach, the electronic spin of a single nitrogen-…
Unconventional phonon blockade via atom-photon-phonon interaction in hybrid optomechanical systems
Mei Wang, Xin-You Lü, Adam Miranowicz +3
Phonon nonlinearities play an important role in hybrid quantum networks and on-chip quantum devices. We investigate the phonon statistics of a mechanical oscillator in hybrid syste…
Disproving hidden variable models with spin magnitude conservation
Pawel Kurzynski, Wieslaw Laskowski, Adrian Kolodziejski +3
The squares of the three components of the spin-s operators sum up to . However, a similar relation is rarely satisfied by the set of possible spin projections onto mutuall…
Experimental measurement of nonlinear entanglement witness by hyper-entangling two-qubit states
Vojtěch Trávníček, Karol Bartkiewicz, Antonín Černoch +1
We demonstrate that non-linear entanglement witnesses can be made particularly useful for entanglement detection in hyper-entangled or multilevel states. We test this idea experime…
Two-color electromagnetically induced transparency via modulated coupling between a mechanical resonator and a qubit
Xin Wang, Adam Miranowicz, Hong-Rong Li +2
We discuss level splitting and sideband transitions induced by a modulated coupling between a superconducting quantum circuit and a nanomechanical resonator. First, we show how to…
Quantum memory and gates using a Lambda-type quantum emitter coupled to a chiral waveguide
Tao Li, Adam Miranowicz, Xuedong Hu +2
By coupling a -type quantum emitter to a chiral waveguide, in which the polarization of a photon is locked to its propagation direction, we propose a controllable photon-emitter…
Implementation of an efficient linear-optical quantum router
Karol Bartkiewicz, Antonín Černoch, Karel Lemr
In this paper, we report on experimental implementation of a linear-optical quantum router. Our device allows single-photon polarization-encoded qubits to be routed coherently into…
Chaotic synchronization of two optical cavity modes in optomechanical systems
Nan Yang, Adam Miranowicz, Yong-Chun Liu +2
The synchronization of the motion of microresonators has attracted considerable attention. Here we present theoretical methods to synchronize the chaotic motion of two optical cavi…
Monogamy of particle statistics in tripartite systems simulating bosons and fermions
Marcin Karczewski, Dagomir Kaszlikowski, Pawel Kurzynski
In the quantum world correlations can take form of entanglement which is known to be monogamous. In this work we show that another type of correlations, indistinguishability, is al…
Experimental tests of coherence and entanglement conservation
Antonín Černoch, Karol Bartkiewicz, Karel Lemr +1
We experimentally demonstrate the migration of coherence between composite quantum systems and their subsystems. The quantum systems are implemented using polarization states of ph…
