Many methods solve Poisson equations by using grid techniques which discretize the problem in each dimension. Most of these algorithms are subject to the curse of dimensionality, so that they need exponential runtime. Researchers at
The quantum computation of electronic energies can break the curse of dimensionality that plagues many-particle quantum mechanics. It is for this reason that a universal quantum computer has the potential to fundamentally change computational chemistry
Preparations are under way for the new Amazon Web Services Center for Quantum Computing, scheduled to open in spring 2021 at Caltech. The two-story, 21,000-square-foot facility will be located on South Holliston Avenue, adjacent to
Rigetti Computing, the quantum computing startup that is challenging industry heavyweights like IBM, Microsoft and D-Wave, announced this week that it has closed a $79 million Series C funding round. The round was led by
Elyah has recently released its online circuit tool to program quantum computers. It comes built-in with a fast in-browser simulator, and a few more perks, like having the option to print your circuits. The tool, Qubit
![Sketch of quantum Go machine. a, Experimental setup of the quantum stone box. The generated photon pairs can be tuned to maximally entangled states, non-maximally entangled states and product states to behave as difierent quantum stones, see Methods. b, The collapse measurement module. After the photons come into this module, they will be measured by the polarizing beam splitter (PBS) then the quantum state collapses to path 1 and 3 (or path 2 and 4). Four single photon detectors transfer the photon signals to electronic signals. c, The time-of-flight storage module. Four output channels from the collapse measurement module will be guided into this module. The collapse result information of each pair of the entangled photons can be acquired aer seing a proper coincidence time window, and recorded as an effective stored state in the time series data. We encode the signals coincidence in Channel 1 and 3 as "1", and Channel 2 and 4 as "0". d, Sketch of playing quantum Go with the quantum stones from the time series data. Two robot arms represent the two agents who help to execute the game of quantum Go together. They pick the quantum stones from the quantum stone box alternately and put every stone onto two intersections of the virtual board. When a quantum stone is put on an intersection that has neighbors, the game will get the collapse results from the time series data with a backdated measurement in the collapse measurement module.
