Microsoft REALLY PICKLED THEMSELVES due to the WAY their technology works! Since I have posted in other forums before about our PARENT company (i.e. NCA - North Canadian Aerospace aka a pseudonym for a Vancouver, British Columbia, Canada-based under-the-radar space-systems and computing company!), I can tell you from PERSONAL EXPERIENCE that using that ridiculous -193 Celcius and below cyrogenic cooling will be the RUIN of all Quantum Computation systems as the introduction of errors and quantum decoherence in literally GUARANTEED by the methods used!
To ENTANGLE and then STORE a quantum state, you need to use a technique originally pioneered by Toshiba Japan (in the 1990's!) and then IBM in hard disk manufacturing where they used MOST LIKELY VALUE based sampling of the magnetic field of a GROUP of rust particles used as spinning disk data storage bit, which allows one to AGGREGATE the MOST-LIKELY CURRENT STATE of a GROUP of bits as the final state value, which is a technique that can now be applied to quantum state values be it a charge, a spin or a position.
In our case, we drill a bunch of holes into a 10 cm by 10 cm flat plate of 5 mm thick Borosilicate Glass using a laser OR electron beam and organize those 300 x 300 x 300 nanometre-sized holes into "Quantum Wells" that are an array of 8192 by 8192 (67,108,864 total wells) which contain trapped Xenon gas (or Argon!) and each hole has a micro-needle jutting a 100 nanometres into the well that is made out of platinum which then goes out to a conductive copper-line-trace which then goes out to a large circular copper plate which can be HIT by a UV laser which will excite the copper and then the platinum needle which then causes a spin state change, a charge change OR a position change of the trapped Xenon or Argon gas molecules using an INFERENCE-based value set or read.
You DO NOT DIRECTLY hit the quantum well itself with a laser but rather use an EXTERNAL FORCE (heat or electrical change in the copper plates and traces!) that SOMEHOW forces (i.e. we are still figuring out the HOW!) a group-based state change which then creates Quantum Value that has super-position (i.e. at least three states and up to 1024 states of value) that could be used as memory storage, emulation of von Neumann microcircuitry, a quantum communications modem OR as actual quantum computation devices AT ROOM TEMPERATURE! No Cryogenic systems are needed!
By organizing a set of wells into a COMBINED GROUP-BASED quantum bit, you can then use 30+ year old Hard Drive digital signal processing techniques to arrive at a Group Concensus as what a given quantum state is assigned to that group of trapped inert gas nano-wells! That group-based sampling, setting and getting is what creates a large Meta-Q-Bit that can then be used in general quantum computation. We go waaaaaaay beyond what D-Wave or IBM or Huawei does and we have the internal proof that STABLE ENTANGLEMENT-based quantum communications and general quantum computationis now possible WITHOUT having to deal with that thorny Quantum Decoherence problem of causing destabilization of a single-Q-bit quantum state into a random value while TRYING to read or write to said quantum well!
We KNOW that a single well has a high liklihood of decohering BUT we also know that at least 25% or more of the wells will STAY STABLE with a value that ON A GROUP-WIDE BASIS points to a specific spin, charge or positional state that IS USABLE as a long-term stable Meta-Q-bit state. At the aggregated throughput of over an Exahertz for the excitation states of individual Xenon or Argon gas molecules trapped within the nanowells, the Stable State Throughput at high sample rates via a pulsed UV laser (i.e. set/get operations) is over a 100 Petabytes per Second for just ONE plate of quantum nanowells!
That is an INSANE amount of computation work that can be done in mere seconds!
Soooooo, Microsoft, D-Wave, IBM, Google, etc should switch over to room-temperature GROUP-CONSENSUS quantum state technologies rather than using cryo-cooled Liquid Helium or Nitrogen to get to stable quantum states of individual Q-bits, and the KEY PART is that the actual device is SIMPLE TO MAKE using common etching systems AND that the materials are inexpensive and that it's all done at ROOM TEMPERATURE!
What's not to like about that?
