On the simple derivation of the Casimir effect
Hai-Chau Nguyen, Matthias Kleinmann
The Casimir effect in its simplest form describes the attraction of two parallel conducting plates at close distance due to the vacuum fluctuation of the electromagnetic field. Its…
Optimised Inference of Quantum Phenomena in High-Energy Collider Experiments
Hai-Chau Nguyen, Gilberto Tetlalmatzi-Xolocotzi, Carmen Diez Pardos +2
Entanglement, a fundamental phenomenon of quantum theory, has recently been observed in processes in high-energy physics. This opens new avenues for probing quantum effects in rela…
On the emergence of classical stochasticity
Xuan Du Trinh, Ismaël Septembre, Hai-Chau Nguyen
We examine the logical structure of the emergence of classical stochasticity for a quantum system governed by a Pauli-type master equation. It is well-known that while such equatio…
Qubits in second quantisation in fermionic simulators
Ahana Ghoshal, Carlos de Gois, Kiara Hansenne +2
Simulating many-body fermionic systems in conventional qubit-based quantum computers poses significant challenges due to the overheads associated with the encoding of fermionic sta…
Structure of quantum measurements implementable with one round of classical communication
Arthur C. R. Dutra, Ties-A. Ohst, Hai-Chau Nguyen +1
Measurements that can be implemented via local operations and classical communication (LOCC) constitute a class of operations that is available in future quantum networks in which…
Quantum memory in spontaneous emission processes
Mei Yu, Ties-A. Ohst, Hai-Chau Nguyen +1
Quantum memory effects are essential in understanding and controlling open quantum systems, yet distinguishing them from classical memory remains challenging. We introduce a convex…
Characterising memory in quantum channel discrimination via constrained separability problems
Ties-A. Ohst, Shijun Zhang, Hai Chau Nguyen +2
Quantum memories are a crucial precondition in many protocols for processing quantum information. A fundamental problem that illustrates this statement is given by the task of chan…
Revealing hidden physical nonclassicality with nonnegative polynomials
Ties-A. Ohst, Benjamin Yadin, Birte Ostermann +3
Understanding quantum phenomena which go beyond classical concepts is a focus of modern quantum physics. Here, we show how the theory of nonnegative polynomials emerging around Hil…
Shadow tomography with noisy readouts
Hai-Chau Nguyen
Shadow tomography is a scalable technique to characterise the quantum state of a quantum computer or quantum simulator. The protocol is based on the transformation of the outcomes…
Dirac exciton-polariton condensates in photonic crystal gratings
Helgi Sigurðsson, Hai Chau Nguyen, Hai Son Nguyen
Bound states in the continuum have recently been utilized in photonic crystal gratings to achieve strong coupling and ultralow power-driven condensation of bosonic exciton-polarito…
Information theoretic approach to readout error mitigation for quantum computers
Hai-Chau Nguyen
We show that the method of iterative bayesian unfolding for mitigating readout errors in quantum computers can be derived from an information theoretic analysis. This inspires more…
Reconfigurable quantum fluid molecules of bound states in the continuum
Antonio Gianfrate, Helgi Sigurdsson, Vincenzo Ardizzone +10
Topological bound states in the continuum are confined wave-mechanical objects that offer advantageous ways to enhance light-matter interactions in compact photonic devices. In par…
