By the middle of the decade, the team from PsiQuantum will have a commercial quantum computer, according to the Financial Times. The founders are also indicating they are ready to emerge from stealth.

PsiQuantum has been mostly silent about its quantum computer development but with its scientific bench composed of leading UK physicists and nearly $300 million in venture capital funding, according to The Quantum Insider, that silence has been deafening.

Pack your bags. We’re going to another galaxy.

NASA now is targeting Oct. 312021, for the launch of the agency’s James Webb Space Telescope from French Guiana.

Webb is designed to discover and study the first stars and galaxies that formed in the early Universe. To see these faint objects, it must be able to detect things that are ten billion times as faint as the faintest stars visible without a telescope. This is 10 to 100 times fainter than Hubble can see.

The successor to Hubble is almost ready for launch. It’s really coming this year, too!

WASHINGTON — A Falcon 9 launched another set of Starlink satellites March 14, with the rocket’s first stage setting a record with its ninth launch and landing.

The Falcon 9 lifted off from Launch Complex 39A at the Kennedy Space Center at 6:01 a.m. Eastern. The upper stage deployed its payload of 60 Starlink satellites into orbit 65 minutes later, bringing the size of the broadband internet constellation to 1260 satellites.

The launch was the eighth for the Falcon 9 this year, and took place a little more than 72 hours after another Falcon 9 launch of Starlink satellites. Six of the eight Falcon 9 launches this year have been dedicated to Starlink, and one of the other two, the Transporter-1 dedicated rideshare flight, also carried 10 Starlink satellites.

CAMBRIDGE, Mass.—(BUSINESS WIRE)—Engineers from HyperLight, a leader in the commercialization of thin-film lithium niobate (LN) photonic integrated circuits (PICs), have achieved breakthrough voltage-bandwidth performances in integrated electro-optic modulators. The broadband electro-optic PIC could lead to orders of magnitude energy consumption reduction for next generation optical networking.

“We believe the significantly improved electro-optic modulation performance in our integrated LN platform will lead to a paradigm shift for both analog and digital ultra-high speed RF links” Tweet this

Energy consumption in optical networking for ethernet, data centers and 5G is soaring as a result of the rapidly growing data traffic. This is because of the limited performance of existing electro-optic modulators, the key element in converting data from the electrical to optical domain at high speed for optical networks. Current electro-optic modulators require extremely high radio-frequency (RF) driving voltages (5 V) as the analog bandwidth in ethernet ports approaches 100 GHz for future terabits per sec capacity transceivers. In comparison, a typical CMOS RF modulator driver delivers less than 0.5 V at such frequencies. Compound semiconductor modulator drivers can deliver voltage 1 V at significantly increased cost and energy consumption but still fall short to meet the optimum driving voltage. The limited voltage-bandwidth performance in electro-optic modulators poses a serious challenge for meeting tight power consumption requirements from network builders.
