Nextbigfuture interviewed Max Perez of ColdQuanta. Max Perez is the Vice President of Research and Security Solutions at ColdQuanta.

ColdQuanta’s cold atom method is a transformational foundational technology platform:

ColdQuanta creates ultra-high vacuum cells that are injected with atoms


Using laser cooling, ColdQuanta cools the atoms to near absolute zero


The system is kept at room temperature while only the atoms remain ultracold, allowing devices to be deployed in rugged environments


Lasers are also used to hold atoms in place and control their quantum states


The key difference among the various end applications of ColdQuanta’s technology is primarily the arrangement of the atoms

They uses lasers to hold atoms in lattices or arrays. For quantum computers, they hold them 3 microns apart. They can hold thousands of atoms. They can use the lasers to reduce the vibrations of the atoms which brings their temperature to absolute zero even though the entire system is at room temperature.

They can create bose einstein condensate on demand.

They are creating new microwave atomic clock and optical clocks. They have three microwave atomic clock programs with different form factors. They are reducing the size (volume) and startup times. The different clocks use different atoms with different frequencies.

The optical clocks will leverage smaller frequency combs to get to 100 times higher accuracy than the main commercial atomic clocks. The main commercial clocks are fridge-sized and cost about $80000.

The Coldquanta clocks have far faster startup. They can be nearly instant startup versus a day or more for commercial atomic clocks to start.

There is the traditional atomic clock market and then there are new markets if a smaller but still highly accurate clock could be made.

Precise time can be used to determine precise position. This is why GPS is based upon atomic clocks. The Military wants portable atomic clocks when the GPS signals are blocked. Every missile and precision munition and military vehicle would need unblockable GPS.

Google uses atomic clocks for the Spanner database. Better atomic clocks could improve the scaling of databases and Google services to enable 100X more database operations per second. Multiple clocks would be needed for every data center.

The technology that ColdQuanta perfects with lasers and atom control and miniturization are needed for all of the other applications. Coldquanta will perfect foundational capabilities and generate significant revenue in this commercial space to open up a far larger universe of atom based technologies. Atomtronics, QuantumRF, error corrected quantum computers with millions or trillions of qubits and much more become possible.

How could ColdQuanta success effect your everyday life? You can get faster communications (higher speed broadband, nextbigfuture will discuss QuantumRF next article), millimeter accurate GPS, hundreds of times higher database transactions and then atomtronics could replace electronics in certain situations. Also, there clearly will be many currently unknown benefits for getting greater and greater control of atoms and light and decreasing the form factors for devices with that control.

Malthus draws strength from sickness in Won’t Go Easy

Multidisciplinary artist Malthus explores childhood trauma, violence and frailty with his debut EP, COUNTRYCIDE, which features contributions from Blackhaine, Sid Quirk, Magnus Westwell and Rainy Miller. Following a string of enigmatic singles, ‘Heroin’, ‘Run Red’ and ‘I Hope For No Cold Shoulder’, each a heady concoction of rusted industrial textures, sparse neoclassical arrangements and chilly…

Canada a 22nd Century Superpower By Being a Great Place to Live

Canada has an 88-page immigration focused plan that would increase Canada’s population to the level of the USA in about 150 years. By 2171, Canada would use good schools, good universities and comfortable quality of life, solid economy to continue attracting high quality immigration to reach a population of about 300 million. This would be…
