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.

A team of researchers affiliated with several institutions in China has developed a form of the board game Go using entanglement. The researchers created a version of quantum Go using entangled photons and found that
As part of the US federal government’s effort to speed the development of quantum computers, the National Science Foundation (NSF) has awarded the University of California, Berkeley, $25 million over five years to establish a multi-university
Researchers at University of Cambridge have presented an interesting paper regarding the usage of Reinforcement Learning to perform Qubit routing in Quantum compilers. Qubit routing refers to the task of modifying quantum circuits so that
Researchers at the University of the Witwatersrand in Johannesburg, South Africa, have demonstrated a record setting quantum protocol for sharing a secret amongst many parties. The team created an 11-dimensional quantum state and used it
A team from JPMorgan Chase, IBM Research Zurich and ETH Zurich presents a methodology to price options and portfolios of options on a gate-based quantum computer using amplitude estimation, an algorithm which provides a quadratic
Researchers from Caltech and Ben-Gurion University put forward the idea that classical blockchains and smart contracts are potentially useful primitives not only for classical cryptography, but for quantum cryptography as well. Abstractly, a smart contract
Miraex, together with top-notch partners Aperio Global and IBM, has been selected among the 15 finalists for the NASA Science Mission Directorate “Entrepreneurs Challenge”. Miraex, a Swiss startup located in Lausanne and spinoff of EPFL, is one of the few
Skoltech scientists have shown that quantum enhanced machine learning can be used on quantum (as opposed to classical) data, overcoming a significant slowdown common to these applications and opening a “fertile ground to develop computational
