Multi-Boson Correlation Sampling
Vincenzo Tamma, Simon Laibacher
We give a full description of the problem of Multi-Boson Correlation Sampling (MBCS) at the output of a random interferometer for single input photons in arbitrary multimode pure s…
Boson sampling with non-identical single photons
Vincenzo Tamma, Simon Laibacher
The boson sampling problem has triggered a lot of interest in the scientific community because of its potential of demonstrating the computational power of quantum interference wit…
Coherent control of quantum systems as a resource theory
J. M. Matera, D. Egloff, N. Killoran +1
Control at the interface between the classical and the quantum world is fundamental in quantum physics. In particular, how classical control is enhanced by coherence effects is an…
Representation-free description of light-pulse atom interferometry including non-inertial effects
Stephan Kleinert, Endre Kajari, Albert Roura +1
Light-pulse atom interferometers rely on the wave nature of matter and its manipulation with coherent laser pulses. They are used for precise gravimetry and inertial sensing as wel…
Quantum state transfer via Bloch oscillations
Dario Tamascelli, Stefano Olivares, Stefano Rossotti +2
The realization of reliable quantum channels, able to transfer a quantum state with high fidelity, is a fundamental step in the construction of scalable quantum devices. In this pa…
The ultimate precision limits for noisy frequency estimation
Andrea Smirne, Jan Kolodynski, Susana F. Huelga +1
Quantum metrology protocols allow to surpass precision limits typical to classical statistics. However, in recent years, no-go theorems have been formulated, which state that typic…
Optimal control of complex atomic quantum systems
S. van Frank, M. Bonneau, J. Schmiedmayer +8
Quantum technologies will ultimately require manipulating many-body quantum systems with high precision. Cold atom experiments represent a stepping stone in that direction: a high…
Steady-state entanglement enhanced by a dissipative ancilla
Joachim Fischbach, Matthias Freyberger
We investigate how to enhance entanglement in the steady state of interacting two-level systems. The steady state is reached by spontaneous decay of the individual systems. When we…
Proposal for high-fidelity quantum simulation using a hybrid dressed state
Jianming Cai, Itsik Cohen, Alex Retzker +1
A fundamental goal of quantum technologies concerns the exploitation of quantum coherent dynamics for the realisation of novel quantum applications such as quantum computing, quant…
A note on coherence power of N-dimensional unitary operators
M. García-Díaz, D. Egloff, M. B. Plenio
The coherence power of a quantum channel, that is, its ability to increase the coherence of input states, is a fundamental concept within the framework of the resource theory of co…
Sensing in the Presence of Observed Environments
M. B. Plenio, S. F. Huelga
Sensing in the presence of environmental noise is a problem of increasing practical interest. In a master equation description, where the state of the environment is unobserved, th…
Crossover from the classical to the quantum Kibble-Zurek scaling
Pietro Silvi, Giovanna Morigi, Tommaso Calarco +1
The Kibble-Zurek (KZ) hypothesis identifies the relevant time scales in out-of-equilibrium dynamics of critical systems employing concepts valid at equilibrium: It predicts the sca…
Efficient simulation of non-Markovian system-environment interaction
Robert Rosenbach, Javier Cerrillo, Susana F. Huelga +2
In this work, we combine an established method for open quantum systems -- the time evolving density matrix using orthogonal polynomials algorithm (TEDOPA) -- with the transfer ten…

We explore theoretically the physics of dynamic hysteresis for driven-dissipative nonlinear photonic resonators. In the regime where the semiclassical mean-field theory predicts bi…
Training Schrödinger's cat: quantum optimal control
Stefffen J. Glaser, Ugo Boscain, Tommaso Calarco +9
It is control that turns scientific knowledge into useful technology: in physics and engineering it provides a systematic way for driving a system from a given initial state into a…

Mischa P. Woods, Martin B. Plenio
Instances of discrete quantum systems coupled to a continuum of oscillators are ubiquitous in physics. Often the continua are approximated by a discrete set of modes. We derive ana…
