The Nobel Prize in Physics 2023 was awarded jointly to Pierre Agostini, Ferenc Krausz and Anne L’Huillier "for experimental methods that generate attosecond pulses of light for the study of electron dynamics in matter".

SoftBank Corp. (“SoftBank”) and LQUOM, Inc. (“LQUOM”) launched a trial to study the communication of entangled photons as a step toward realizing a quantum Internet. The field study will transmit entangled photons through optical fiber in the Tokyo Metropolitan Area. The optical fiber of this study links SoftBank's headquarters and its data center in the Tokyo Metropolitan Area. LQUOM will integrate a quantum communication system with the field fiber. Accordingly, SoftBank and LQUOM will investigate quantum communication technology in a practical environment in the Tokyo Metropolitan Area.

Toshiba has officially opened the new, cutting edge Quantum Technology Centre in a ceremony attended by Lord Johnson, Minister of Investment in the Department for Business and Trade for the UK Government, and Hajime Hayashi, Ambassador of Japan to the United Kingdom. The new facility, located in the Cambridge Science Park, is a commercial offshoot from the Toshiba Cambridge Research Laboratory and represents a £20 million investment from Toshiba into the development of quantum-secure networking solutions and will initially create over 30 new jobs in high-technology industry.

Long-distance quantum communication can be achieved by directly sending light through space using a train of orbiting satellites that function as optical lenses.

The U.S. Department of Energy (DOE) announced $24 million in funding for three collaborative projects in quantum network research.

The International Organization for Standardization (ISO) has introduced its inaugural set of standards dedicated to Quantum Key Distribution (QKD) security requirements.

Vodafone and SandboxAQ conducted a proof-of-concept test for a quantum-safe Virtual Private Network (VPN)

HSBC is the first bank to join BT and Toshiba’s pioneering commercial quantum secure metro network, working in collaboration with Amazon Web Services (AWS)

Vithas, the only hospital group participating in Madrid Quantum, will test the security of patient health data and the accuracy and reliability of quantum communication in remote surgeries and other telemedicine services

At the ATxSummit Social, part of Asia Tech x Singapore (ATxSG), the region’s most influential technology event, Singapore’s Deputy Prime Minister, Mr. Heng Swee Keat, announced the launch of the National Quantum-Safe Network Plus (NQSN+) which aims to deliver quantum-safe communications across Singapore.
