Simulating quantum transport via collisional models on a digital quantum computer
Rebecca Erbanni, Xiansong Xu, Tommaso Demarie +1
Digital quantum computers have the potential to study the dynamics of complex quantum systems. Nonequilibrium open quantum systems are, however, less straightforward to be implemen…
OpenQAOA -- An SDK for QAOA
Vishal Sharma, Nur Shahidee Bin Saharan, Shao-Hen Chiew +4
We introduce OpenQAOA, a Python open-source multi-backend Software Development Kit to create, customise, and execute the Quantum Approximate Optimisation Algorithm (QAOA) on Noisy…
Cross-verification of independent quantum devices
C. Greganti, T. F. Demarie, M. Ringbauer +13
Quantum computers are on the brink of surpassing the capabilities of even the most powerful classical computers. This naturally raises the question of how one can trust the results…
Client-friendly continuous-variable blind and verifiable quantum computing
Nana Liu, Tommaso F. Demarie, Si-Hui Tan +2
We present a verifiable and blind protocol for assisted universal quantum computing on continuous-variable (CV) platforms. This protocol is highly experimentally-friendly to the cl…
Classical verification of quantum circuits containing few basis changes
Tommaso F. Demarie, Yingkai Ouyang, Joseph F. Fitzsimons
We consider the task of verifying the correctness of quantum computation for a restricted class of circuits which contain at most two basis changes. This contains circuits giving r…
Flow Ambiguity: A Path Towards Classically Driven Blind Quantum Computation
Atul Mantri, Tommaso F. Demarie, Nicolas C. Menicucci +1
Blind quantum computation protocols allow a user to delegate a computation to a remote quantum computer in such a way that the privacy of their computation is preserved, even from…
Universality of quantum computation with cluster states and (X,Y)-plane measurements
Atul Mantri, Tommaso F. Demarie, Joseph F. Fitzsimons
Measurement-based quantum computing (MBQC) is a model of quantum computation where quantum information is coherently processed by means of projective measurements on highly entangl…
Anonymous broadcasting of classical information with a continuous-variable topological quantum code
Nicolas C. Menicucci, Ben Q. Baragiola, Tommaso F. Demarie +1
Broadcasting information anonymously becomes more difficult as surveillance technology improves, but remarkably, quantum protocols exist that enable provably traceless broadcasting…
Geometrical and Topological Aspects of Quantum Information Systems
Tommaso F. Demarie
In this Thesis we examine the interplay between the encoding of information in quantum systems and their geometrical and topological properties. We first study photonic qubit probe…
Detecting Topological Entanglement Entropy in a Lattice of Quantum Harmonic Oscillators
Tommaso F. Demarie, Trond Linjordet, Nicolas C. Menicucci +1
The Kitaev surface-code model is the most studied example of a topologically ordered phase and typically involves four-spin interactions on a two-dimensional surface. A universal s…
Pedagogical introduction to the entropy of entanglement for Gaussian states
Tommaso F. Demarie
The most useful measure of a bipartite entanglement is the von Neumann entropy of either of the reduced density matrices. For a particular class of continuous-variable states, the…
Entropy and entanglement in polymer quantization
Tommaso F. Demarie, Daniel R. Terno
Polymer quantization is as a useful toy model for the mathematical aspects of loop quantum gravity and is interesting in its own right. Analyzing entropies of physically equivalent…
Fundamental quantum optics experiments conceivable with satellites -- reaching relativistic distances and velocities
David Rideout, Thomas Jennewein, Giovanni Amelino-Camelia +14
Physical theories are developed to describe phenomena in particular regimes, and generally are valid only within a limited range of scales. For example, general relativity provides…
Photon polarization and geometric phase in general relativity
Aharon Brodutch, Tommaso F. Demarie, Daniel R. Terno
Rotation of polarization in an external gravitational field is one of the effects of general relativity that can serve as a basis for its precision tests. A careful analysis of ref…
