A consortium of scientists, including from RMIT University and University of Adelaide, is using hybrid diamond and glass technology to make a new class of quantum sensors. By embedding micron-scale diamond particles within the cross
The Gravity Delve project, funded by Innovate UK, brings together academics from the UK Quantum Technology Hub Sensors and Timing, which is led by the University of Birmingham and Nemein Ltd, with the aim of investigating
Researchers at University of Sydney Nano Institute have developed the first system-wide quantum algorithm to characterize noise. Noise is the main obstacle to building large-scale quantum computers. To tame the noise (interference or instability), scientists
A new theoretical study identifies fundamental tradeoffs that limit the amount of noise reduction in quantum information systems. Quantum information technology could perform certain tasks faster and more securely than classical methods, but noise is
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
![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.
