Telex: Long-distance quantum transmission on fiber, ChapsVision crunches Bertin IT and Vecsys, Patrick Drahi majority at BT

– Long-distance quantum communication over fiber. Toshiba’s research laboratory in Cambridge has demonstrated for the first time quantum communication over a fiber-optic network of more than 600 km. The goal is to create a network capable of interconnecting a set of quantum computers around the world. Transmitting qbits over long distances is a challenge in itself, as they are sensitive to temperature variations that constrict or stretch optical fibers. Scientists have invented a technique called “dual band stabilization”. This method involves sending two signals through the optical fiber at different wavelengths. The former is used to quickly eliminate variations, while the latter, similar to qubits, stabilizes the flow. The test focused on the dissemination of a quantum key distribution (QKD) to secure qubit-based communications.

– ChapsVision acquires Bertin IT and Vecsys. Previously owned by CNIM (naval and industrial constructions of the Mediterranean), Bertin IT and Vecsys have just been sold to the French ChapsVision. Bertin IT offers cybersecurity monitoring software called AMI EI (used in particular by SNCF) and OSINT with MediaCentric. For its part, Vecsys is a specialist in voice recognition. The two companies will enrich the portfolio of ChapsVision, expert in data analysis software for companies and organizations.

– Patrick Drahi majority at BT. The telecoms tycoon has just struck a blow by announcing to hold 12.1% of the British incumbent operator via a subsidiary created specifically Altice UK. Through this structure, he paid £ 2.2 billion to acquire 1.2 million shares of BT. Patrick Drahi therefore extends his telecom empire with a presence in France (via SFR), Israel, the United States, Spain and Portugal. In Great Britain, Patrick Drahi wants to participate in the development of optical fiber, because the country is lagging behind in this area.

– Long-distance quantum communication over fiber. Toshiba’s analysis laboratory in Cambridge has demonstrated for the primary time quantum communication over a fiber-optic community of greater than 600 km. The objective is to create a community able to interconnecting a set of quantum computer systems world wide. Transmitting qbits over lengthy distances is a problem in itself, as they’re delicate to temperature variations that constrict or stretch optical fibers. Scientists have invented a method known as “twin band stabilization”. This methodology includes sending two alerts by way of the optical fiber at totally different wavelengths. The previous is used to shortly get rid of variations, whereas the latter, much like qubits, stabilizes the circulation. The take a look at targeted on the dissemination of a quantum key distribution (QKD) to safe qubit-based communications.

– ChapsVision acquires Bertin IT and Vecsys. Beforehand owned by CNIM (naval and industrial constructions of the Mediterranean), Bertin IT and Vecsys have simply been bought to the French ChapsVision. Bertin IT presents cybersecurity monitoring software program known as AMI EI (utilized in specific by SNCF) and OSINT with MediaCentric. For its half, Vecsys is a specialist in voice recognition. The 2 firms will enrich the portfolio of ChapsVision, skilled in information evaluation software program for firms and organizations.

By this construction, he paid £ 2.2 billion to amass 1.2 million shares of BT. Patrick Drahi subsequently extends his telecom empire with a presence in France (through SFR), Israel, the USA, Spain and Portugal. In Nice Britain, Patrick Drahi desires to take part within the growth of optical fiber, as a result of the nation is lagging behind on this space.
