Pointers toward the future of Quantum Computing…

I got quoted in this PhysicsWorld article:

Single atoms go transparent – PhysicsWorld April 21st 2010

The article was written in response to an ArXiv’ed paper from Nakamura’s group who investigate superconducting qubits (usually of the charge variety) in this case coupled to a microwave transmission line:

Electromagnetically induced transparency on a single artificial atom

From the article:

“Making an opaque material transparent might seem like magic. But for well over a decade, physicists have been able to do just that in atomic gases using the phenomenon of electromagnetically induced transparency (EIT). Now, however, this seemingly magical effect has been observed in single atoms – and in “artificial” atoms consisting of a superconducting loop – for the first time. “

I made the point in the article that combining flying qubits (basically entangled photons) which have the advantanges of long decoherence times and easy transportation of information, with solid-state implementations such as superconducting loops (good at storage and high-fidelity readout) would be a great step forwards in the generation of scalable architectures for quantum computing. Of course, I am slightly more biased towards the adiabatic QC approach at the moment (go figure) but there’s no reason why these developments couldn’t lead to some awesome hybrid quantum circuits involving a combination of gate model solid-state, AQC solid state and flying qubits. We just need to figure out how to put all the pieces together.

    PhysicsWorld did a good job writing this up.
    Add to this the fact that the Yale and Santa Barbara people just a few weeks ago simultaneously achieved 3 qubit entanglement with JJs. and I’d say your field is superhot right now

      Hi RR, Thanks for reminding me about those two papers, I meant to write a post about them! Superconducting Flux Qubits FTW!!!
