Ultrafast non-destructive measurement of the quantum state of light using free electrons

Alexey Gorlach, Aviv Karnieli, Raphael Dahan +3

Since the birth of quantum optics, the measurement of quantum states of nonclassical light has been of tremendous importance for advancement in the field. To date, conventional det…

The first detection time of a quantum state under random probing

David A. Kessler, Eli Barkai, Klaus Ziegler

We solve for the statistics of the first detection of a quantum system in a particular desired state, when the system is subject to a projective measurement at independent identica…

Randomly repeated measurements on quantum systems: Correlations and topological invariants of the quantum evolution

K. Ziegler, E. Barkai, D. Kessler

Randomly repeated measurements during the evolution of a closed quantum system create a sequence of probabilities for the first detection of a certain quantum state. The related di…

Broadband complex two-mode quadratures for quantum optics

Leon Bello, Yoad Michael, Michael Rosenbluh +2

In their seminal paper, Caves and Schumaker presented a new formalism for quantum optics, intended to serve as a building block for describing two-photon processes, in terms of new…

Response theory for nonequilibrium steady-states of open quantum systems

Amikam Levy, Eran Rabani, David T. Limmer

We introduce a response theory for open quantum systems within nonequilibrium steady-states subject to a Hamiltonian perturbation. Working in the weak system-bath coupling regime,…

Experimental tests of Multiplicative Bell Inequalities

Dilip Paneru, Amit Te'eni, Bar Y. Peled +5

Bell inequalities are mathematical constructs that demarcate the boundary between quantum and classical physics. A new class of multiplicative Bell inequalities originating from a…

Correlation Minor Norms, Entanglement Detection and Discord

Bar Y. Peled, Amit Te'eni, Avishy Carmi +1

In this paper we develop an approach for detecting entanglement, which is based on measuring quantum correlations and constructing a correlation matrix. The correlation matrix is t…

Non-Hermitian and Zeno limit of quantum systems under rapid measurements

Felix Thiel, David A. Kessler

We investigate in depth the relation between the first detection time of an isolated quantum system that is repeatedly perturbed by strong local measurements with a large fixed fre…

Identification of symmetry-protected topological states on noisy quantum computers

Daniel Azses, Rafael Haenel, Yehuda Naveh +3

Identifying topological properties is a major challenge because, by definition, topological states do not have a local order parameter. While a generic solution to this challenge i…

Double Slit with an Einstein-Podolsky-Rosen Pair

Bar Y. Peled, Amit Te'eni, Danko Georgiev +2

In this somewhat pedagogical paper we revisit complementarity relations in bipartite quantum systems. Focusing on continuous variable systems, we examine the influential class of E…
