Quantum Sensing with Driven-Dissipative Su-Schrieffer-Heeger Lattices
Oscar Arandes, Emil J. Bergholtz
The remarkable sensitivity of non-Hermitian systems has been extensively studied and stimulated ideas about developing new types of sensors. In this paper, we examine a chain of pa…
Isoholonomic inequality and tight implementations of holonomic quantum gates
Ole Sönnerborn
In holonomic quantum computation, quantum logic gates are realized by cyclic parallel transport of the computational space. The resulting quantum gate corresponds to the holonomy a…
Hamiltonian characterisation of multi-time processes with classical memory
Kaumudibikash Goswami, Abhinash Kumar Roy, Varun Srivastava +4
A central problem in open quantum systems is the characterization of non-Markovian processes, where an environment retains the memory of its interaction with the system. A key dist…
The Gravito-Phononic Effect: A Quantum Signature of Linearised Gravity
Germain Tobar, Oscar Berg
The photo-electric effect was a historic milestone in the development of quantum theory, revealing the first evidence of discrete energy of the electromagnetic field through hallma…
Generalized measurements on qubits in quantum randomness certification and expansion
Piotr Mironowicz, Marcus Grünfeld, Mohamed Bourennane
Quantum mechanics has greatly impacted our understanding of the microscopic nature. One of the key concepts of this theory is generalized measurements, which have proven useful in…
Bounding conditional entropy of bipartite states with Bell operators
Jan Horodecki, Piotr Mironowicz
Quantum information theory explores numerous properties that surpass classical paradigms, offering novel applications and benefits. Among these properties, negative conditional von…
