LIDS researchers Maison Clouâtré, Stefano Marano, Andrea Conti, Peter L. Falb, and Moe Z. Win have received a best paper award at the 2025 International Conference on Quantum Communications, Networking, and Computing (QCNC 2025) for their paper “Optimal quantum state discrimination with fixed measurements.”
The need for accurate state discrimination arises in a myriad of emerging quantum technologies, spanning the domains of sensing, communication, computing, and decision making. In their paper, the LIDS researchers establish a mathematical foundation for quantum state discrimination in physical scenarios where the measurement apparatus is fixed. They advocate the use of quantum pre-processing (QPP) to optimize state discrimination performance in such scenarios, derive the fundamental limits of state discrimination with fixed measurements, and determine optimal QPP to achieve these limits.
This paper is the latest effort of Win’s (AA, LIDS, SCC) newly established Quantum neXus Laboratory (QX Lab) situated within LIDS. Since its inception, LIDS has been at the forefront of research in the fields of communication theory, information theory, systems and control, and communications networks. “Harnessing LIDS-style thinking, QX Lab is aiming to make new contributions in the quantum domain,” Win says. Win’s coauthors on this paper are Clouâtré (a second-year graduate student in AA, QX Lab, and LIDS) as well as Marano, Conti, and Falb (LIDS research affiliates).
QCNC provides a forum for academic researchers and industry practitioners to present research progress, exchange new ideas, and identify future directions in the field of Quantum Communications, Networking, and Computing. QCNC is sponsored by the IEEE Communications Society. This year, QCNC was held in Nara, Japan, on March 31 – April 2, 2025.
