Google has a significant research effort in Quantum Computing.    They have been working together with NASA and the Universities Space Research Association (USRA) to operate first a DWave 2 and now a DWave 2X processor at the NASA Ames Research Center in Mountain View, California.   Google has recently published a benchmarking paper on the DWave 2X showing initial test results.    In 2014, Google started up a second effort by hiring John Martinis and his group at UC Santa Barbara to work on a quantum computer that utilizes some of the surface code error correction technology that they have developed.   This technology has already exhibited major improvements in coherence time that could significantly improve a quantum computer’s performance.   Google has been vague about the ultimate goal but it is clear there could be significant applications in machine learning, pattern recognition, and other areas relevant to Google’s main endeavors.

Honeywell has created a Honeywell Quantum Solutions group that is working to leverage Honeywell’s vast experience in electronics, optics, mechanical systems, software, and control systems to develop a quantum processor based upon Ion Trap technology. They use the term “Nature’s Qubit” for the system and believe their technology allows the qubits to be more uniform and controlled more easily than alternative technologies. At a recent technical conference, Honeywell showed average qubit fidelity measurements of 99.9967% on single qubit gates and 99.89% on two cubit gates. Although we believe this was on a small number of qubits, these are the best fidelity numbers we have seen so far from anyone. Their target is to offer a system on which people can access to test their algorithms before the end of 2019.

IBM research has a quantum computing group at their Yorktown Heights, New York, research center.   IBM’s approach appears to be based upon utilization of superconducting circuits coupled with error correction.   In April 2015, they announced an advance with a circuit that can detect both bit-flip and phase-flip errors together.  Most recently in December 2015, IBM was awarded an iARPA grant to use this technology under the Logical Qubits (LogiQ) program to overcome the limitation of current quantum systems by building a logical qubit from a number of imperfect physical qubits.

Although Intel previously did not have any research efforts devoted to quantum computing they did just commit to provide QuTech, the quantum research institute of Delft University of Technology (TU Delft) and the Dutch Organisation of Applied Research (TNO), with $50 million in funding and provide engineering support over a ten years collaboration to support their efforts.    A press kit describing Intel’s activities in quantum computing can accessed here.   Many people have been forecasting that Moore’s Law will end at some point and it seems that Intel wanted to hedge their bets on this new technology.
