Experimentally determining the incompatibility of two qubit measurements
Andrea Smirne, Simone Cialdi, Daniele Cipriani +3
We describe and realize an experimental procedure for assessing the incompatibility of two qubit measurements. The experiment consists in a state discrimination task where either m…
Stochastic collisional quantum thermometry
Eoin O'Connor, Bassano Vacchini, Steve Campbell
We extend collisional quantum thermometry schemes to allow for stochasticity in the waiting time between successive collisions. We establish that introducing randomness through a s…

We present a control and measurement setup for superconducting qubits based on Xilinx 16-channel radio-frequency system-on-chip (RFSoC) device. The proposed setup consists of four…
Extracting work from random collisions: A model of a quantum heat engine
Vahid Shaghaghi, G. Massimo Palma, Giuliano Benenti
We study the statistical distribution of the ergotropy and of the efficiency of a single-qubit battery ad of a single-qubit Otto engine, respectively fuelled by random collisions.…
Cost-effective temperature estimation strategies for thermal states with probabilistic quantum metrology
Massimo Frigerio, Stefano Olivares, Matteo G. A. Paris
In probabilistic quantum metrology, one aims at finding weak measurements that concentrate the Fisher Information on the resulting quantum states, post-selected according to the we…

Mostafa Annabestani, Majid Hassani, Dario Tamascelli +1
We address multi-parameter quantum estimation for one-dimensional discrete-time quantum walks and its applications to quantum metrology. We use the quantum walker as a probe for un…
Fragmented imaginary-time evolution for early-stage quantum signal processors
Thais de Lima Silva, Márcio M. Taddei, Stefano Carrazza +1
Simulating quantum imaginary-time evolution (QITE) is a major promise of quantum computation. However, the known algorithms are either probabilistic (repeat until success) with imp…

In a recent paper we have described an optical implementation of a measure-once one-way quantum finite automaton recognizing a well-known family of unary periodic languages, accept…
Quantum guessing games with posterior information
Claudio Carmeli, Teiko Heinosaari, Alessandro Toigo
Quantum guessing games form a versatile framework for studying different tasks of information processing. A quantum guessing game with posterior information uses quantum systems to…
Multiclass classification of dephasing channels
