Towards fault-tolerant quantum computation with universal continuous-variable gates
Sheron Blair, Francesco Arzani, Giulia Ferrini +1
Continuous-variable (CV) systems have shown remarkable potential for quantum computation, particularly excelling in scalability and error correction through bosonic encoding. Withi…
Exploiting symmetry in variational quantum machine learning
Johannes Jakob Meyer, Marian Mularski, Elies Gil-Fuster +4
Variational quantum machine learning is an extensively studied application of near-term quantum computers. The success of variational quantum learning models crucially depends on f…
Gottesman-Kitaev-Preskill codes: A lattice perspective
Jonathan Conrad, Jens Eisert, Francesco Arzani
We examine general Gottesman-Kitaev-Preskill (GKP) codes for continuous-variable quantum error correction, including concatenated GKP codes, through the lens of lattice theory, in…
Bloch-Messiah reduction for twin beams of light
D. B. Horoshko, L. La Volpe, F. Arzani +3
We study the Bloch-Messiah reduction of parametric downconversion of light in the pulsed regime with a nondegenerate phase matching providing generation of twin beams. We find that…
High-dimensional quantum encoding via photon-subtracted squeezed states
Francesco Arzani, Alessandro Ferraro, Valentina Parigi
We introduce a high-dimensional quantum encoding based on coherent mode-dependent single-photon subtraction from multimode squeezed states. This encoding can be seen as a generaliz…
Random coding for sharing bosonic quantum secrets
Francesco Arzani, Giulia Ferrini, Frédéric Grosshans +1
We consider a protocol for sharing quantum states using continuous variable systems. Specifically we introduce an encoding procedure where bosonic modes in arbitrary secret states…
Violating Bell inequalities with entangled optical frequency combs and multi-pixel homodyne detection
William N. Plick, Francesco Arzani, Nicolas Treps +2
We have theoretically investigated the possibility of using any of several continuous-variable Bell-type inequalities - for which the dichotomic measurements are achieved with coar…
Versatile engineering of multimode squeezed states by optimizing the pump spectral profile in spontaneous parametric down-conversion
Francesco Arzani, Claude Fabre, Nicolas Treps
We study the quantum correlations induced by spontaneous parametric down-conversion (SPDC) of a frequency comb. We derive a theoretical method to find the output state correspondin…
Reconfigurable optical implementation of quantum complex networks
Johannes Nokkala, Francesco Arzani, Fernando Galve +5
Network theory has played a dominant role in understanding the structure of complex systems and their dynamics. Recently, quantum complex networks, i.e. collections of quantum syst…
Polynomial approximation of non-Gaussian unitaries by counting one photon at a time
Francesco Arzani, Nicolas Treps, Giulia Ferrini
In quantum computation with continous-variable systems, quantum advantage can only be achieved if some non-Gaussian resource is available. Yet, non-Gaussian unitary evolutions and…
Reconfigurable Optical Quantum Networks Using Multimode Quantum Frequency Combs and Pulse Shaping
Y. Cai, J. Roslund, G. Ferrini +4
Multimode entanglement is quintessential for the design and fabrication of quantum networks, which play a central role in quantum information processing and quantum metrology. Howe…
A direct approach to Gaussian measurement based quantum computation
Giulia Ferrini, Jonathan Roslund, Francesco Arzani +2
In this work we introduce a general scheme for measurement based quantum computation in continuous variables. Our approach does not necessarily rely on the use of ancillary cluster…
Optimization of networks for measurement-based quantum computation
G. Ferrini, J. Roslund, F. Arzani +3
This work introduces optimization strategies to continuous variable measurement based quantum computation (MBQC) at different levels. We provide a recipe for mitigating the effects…
