WQC: the Common Purpose - meeting the quantum computing challenge...


The question isn't why do we want one,

 it is how do we build one…

There are many ways imagined to construct a quantum computer. But which way is best? Each proposal comes with limitations and drawbacks. The QCWG team pursues an approach that is radically different, riskier, and with greater payoffs than those commonly employed in the field. 


The QCWG approach is NOT a change to circuit QED, or the use of different vacancies in optical interactions. It isnt incremental and it isn't subtle. It IS, instead, a pathway to take quantum bits, registers, and processors from their 5 mK coolers and put them into room temperature devices. Using the symmetry preserving properties of complex topologies constructed on 2D manifolds (known as the stabilization conjecture) robust Qubits/Quregisters can be constructed that allow for significant hardness against the environment. 

This is the core behind - WQC - an attempt at realizing this architecture for general processing.


Where are we: Progress?


06/21 - First quantum elements were synthesized and proven to work. Characterization, modification, etc.     underway. The SQUIRL was born.

12/21 - Design began on first ringer, a QED circuit for use with a SQUIRL at rf.

03/22 - 1st masks delivered for rf ringers, now the real lithography begins


06/22 - resonant response measured in the rf ringers for the first time. 1st signal!

07/22 - Direct observation of persistent currents using MFM


08/22 - CNOT gate design of mask begins. Simulations reveal requirements for impedance matching

08/22 - 1st heterogeneous integration with SQUIRL

11/22 - First time-crystal signal from a simple TI! Never before observed in such a topological system. Promising for use in quantum memories.

10/23 - First Integration of SQUIRLS into a five Qubit register
