Scott Aaronson has commented about the Dwave paper that was published in Nature. (Quantum annealing with manufactured spins) In the new work, they apply an annealing operation to eight coupled qubits arranged in a 1D chain, then plot the probability of a particular basis state as a function of time, by running the experiment over …
Dwave has had their 128 qubit adiabatic quantum computer chip for some time It is a 4×4 array of 8-qubit unit cell Just a few days ago Dwave published a peer reviewed article in the prestigious journal Nature that confirms that their 8 qubit unit cells are leveraging quantum effects. So proving the 8 qubit …
A Dwave systems, adiabatic quantum computer, critic (Chris Lee at Ars Technica) has retracted statement that Dwave was borderline fraudulent. Geordie and friends, I am sorry. I don’t know if you have a working device, but the theoretical work produced by D-Wave is sharp and a great indication that you are honestly pursuing your stated …
A circuit of four superconducting qubits. Scientists have succeeded in entangling three of these. Yale work published in Nature NY Times reports that I.B.M. has reconstituted what had recently been a relatively low-level research effort in quantum computing. I.B.M. is responding to advances made in the past year at Yale University and the University of …

Aug, 2008 [71 pages] Some of the categories of algorithms: Factoring, Discrete Logarithms and the Abelian Hidden Subgroup Problem : like Shor’s algorithm. Quantum Walk …
Dwave’s CTO Geordie Rose is showing a picture of a 200mm wafer made of 5mm superconducting adiabatic quantum computing chips. There are about 1000 of the 5mm chips on the wafer. The superconducting adiabatic quantum computing chips need dilution fridges for proper operationUsing a dilution refrigerator is the most powerful way to reach very low …
Dwave Systems closed a $17M financing round as of the end of January 2008. These funds will be used primarily to push the level of integration of our chips into the low thousands of qubits by the end of the year. In parallel with this central effort we will be working on running experiments on …
Robert Bussard Inertial Electrostatic Fusion work The gear from the last round of testing are with Jim Benson of Spacedev in San Diego.More info on Robert Bussard’s Inertial confinement fusion It would take $250 million and 5 years to create a full scale demonstration plant which should be able to produce more power than it …
I have made a long bet prediction. This costs $50. Anyone is free to challenge this prediction and a long bet can be negotiated. There will be a quantum computer with over 100 qubits of processing capability sold either as a hardware system or whose use is made available as a commercial service by Dec …
