Knut and Alice Wallenberg Foundation is almost doubling the annual budget of the research initiative Wallenberg Centre for Quantum Technology, based at Chalmers University of Technology, Sweden. This will allow the center to shift up a gear and set even higher goals – especially in its development of a quantum computer. Two international workshops will kick-start this new phase.

”Quantum technology has enormous potential and it is important that Sweden has the necessary skills in the area. During the short time

Honeywell’s quantum scientists have quadrupled the capabilities of the company’s quantum computer, with the device achieving record levels of performance less than a year after the first generation of the system was released.  

The System Model H1, a ten-qubit quantum computer, effectively reached a quantum volume of 512 – four times as much as was attained in the previous tweak of the system, which saw the H1 reach a quantum volume of 128.  

Released commercially last June (at the time as the System

Quantum Computer Start-up IonQ Plans IPO via SPAC

IonQ, a Maryland-based quantum computing start-up working with ion trap technology, plans to go public via a Special Purpose Acquisition Company (SPAC) merger according to a report in today’s Wall Street Journal. The deal would value IonQ at $2 billion and make it the first pure-play quantum computing company to go public.

SPACs aren’t new but have recently become more popular. In this deal IonQ would merge with the ‘blank check’ firm dMY Technology Group. Here’s a quick description of the SPAC methodology from Investopedia:

“SPACs are generally formed by investors, or sponsors, with expertise in a particular industry or

Europe seeks semiconductor boost, first quantum computer

BRUSSELS (Reuters) – The European Union wants to produce a fifth of the global output of cutting-edge semiconductors at the end of this decade and make its first quantum computer in five years, as part of efforts to cut its dependence on non-European technologies.

The EU plan called 2030 Digital Compass comes as the COVID-19 pandemic exposes the 27-country bloc’s reliance on key technologies owned by Chinese and U.S. companies.

The plan cited the importance

Programmable optical quantum computer arrives late, steals the show

Excuse me a moment—I am going to be bombastic, over excited, and possibly annoying. The race is run, and we have a winner in the future of quantum computing. IBM, Google, and everyone else can turn in their quantum computing cards and take up knitting.

OK, the situation isn’t that cut and dried yet, but a recent paper has described a fully programmable, chip-based optical quantum computer. That idea presses all my buttons, and until someone restarts me, I will talk of nothing else.

Love the light

There is no question that quantum computing has come a long way

Pivotal Discovery Could Open New Field of Quantum Technology Called “Magnonics”

A technological breakthrough could enable a new field of quantum technology called “magnonics,” by successfully pairing two types of quantum particles called microwave photons and magnons.

University of Chicago, Argonne scientists tame photon-magnon interactions

In a first-of-its-kind discovery, researchers in the University of Chicago’s Pritzker School of Molecular Engineering and Argonne National Laboratory announced they can directly control the interactions between two types of quantum particles called microwave photons and magnons. The approach may become a new way to build quantum technology, including electronic devices with new capabilities. 

Scientists have high hopes for quantum technology, which has advanced by
