  • Building a better clock December 12, 2019
    Thursday, December 12, 2019 The best clocks in the world can keep time so accurately that they only lose one second in millions or even billions of years. Yet, researchers are still fervently pursuing ever better clocks. Once a certain threshold of clock accuracy and stability is crossed, it will open up tremendous opportunities to […]
  • Heat energy leaps through empty space, thanks to quantum weirdness December 11, 2019
    A surprising new study shows that heat energy can leap across a few hundred nanometers of a complete vacuum, thanks to a quantum mechanical phenomenon called the Casimir interaction. Though this interaction is only significant on very short length scales, it could have profound implications for the design of computer chips and other nanoscale electronic […]
  • New laser technique images quantum world in a trillionth of a second December 10, 2019
    For the first time, researchers have been able to record, frame-by-frame, how an electron interacts with certain atomic vibrations in a solid. The technique captures a process that commonly causes electrical resistance in materials while, in others, can cause the absence of resistance, or superconductivity.
  • Why Quantum Startups are Hooking Up with Classical Computer Companies December 7, 2019
    We are now starting to see more and more relationships between established classical computer companies and quantum startups.  Recently we’ve seen Microsoft ink cloud partnerships with IonQ, Honeywell, and QCI; Amazon announce partnerships with Rigetti, IonQ, and D-Wave; and Atos start working with Zapata.  There are good reasons why these classical/quantum relationships are forming and […]
  • Gamma-ray laser moves a step closer to reality December 6, 2019
    A physicist has performed calculations showing hollow spherical bubbles filled with a gas of positronium atoms are stable in liquid helium. The calculations take scientists a step closer to realizing a gamma-ray laser.
  • A platform for stable quantum computing, a playground for exotic physics December 5, 2019
    Researchers have demonstrated the first material that can have both strongly correlated electron interactions and topological properties, which not only paves the way for more stable quantum computing but also an entirely new platform to explore the wild world of exotic physics.
  • A new carbon nanotube-based filter for quantum computing applications December 4, 2019
    Wednesday, December 4, 2019
  • Amazon Enters the Quantum Computing Business December 3, 2019
    In a multi-pronged thrust, Amazon through its Amazon Web Services (AWS) division will be entering the quantum business via cloud services, research, and consulting services. The quantum computing cloud service is called Amazon Braket and provide access to quantum computers from D-Wave, IonQ, and Rigetti, with more to be added in the future. It will […]
  • Cloud Platform Hardware Partners December 3, 2019
    With the recent announcements from IBM, Microsoft and Amazon that they will be supporting multiple different hardware vendors and technologies on their platforms, it is getting complicated to know who is partnering with whom. So we have created a table showing Cloud/Hardware partners in a manner similar to our other table which shows Software Partners. […]
  • Two updates December 2, 2019
    Two weeks ago, I blogged about the claim of Ohad Keller and Nathan Klein to have proven the Aaronson-Ambainis Conjecture. Alas, Keller and Klein tell me that they’ve now withdrawn their preprint (though it may take another day for that to show up on the arXiv), because of what looks for now like a fatal […]
  • Toward more efficient computing, with magnetic waves November 28, 2019
    Researchers have devised a novel circuit design that enables precise control of computing with magnetic waves -- with no electricity needed. The advance takes a step toward practical magnetic-based devices, which have the potential to compute far more efficiently than electronics.
  • Building a better battery with machine learning November 27, 2019
    Researchers have turned to the power of machine learning and artificial intelligence to dramatically accelerate battery discovery.
  • Guest post by Greg Kuperberg: Archimedes’ other principle and quantum supremacy November 26, 2019
    Scott’s Introduction: Happy Thanksgiving! Please join me in giving thanks for the beautiful post below, by friend-of-the-blog Greg Kuperberg, which tells a mathematical story that stretches from the 200s BC all the way to Google’s quantum supremacy result last month. Archimedes’ other principle and quantum supremacy by Greg Kuperberg Note: UC Davis is hiring in […]
  • Milestone in quantum standardization November 25, 2019
    Researchers have developed a method that could pave the way to establishing universal standards for measuring the performance of quantum computers. The new method, called cycle benchmarking, allows researchers to assess the potential of scalability and to compare one quantum platform against another.
  • Ultrafast quantum simulations: A new twist to an old approach November 25, 2019
    Billions of tiny interactions occur between thousands of particles in every piece of matter in the blink of an eye. Simulating these interactions in their full dynamics was said to be elusive but has now been made possible.
  • Benchmarking scalability and performance of quantum computers November 25, 2019
    Monday, November 25, 2019 Researchers at the Institute for Quantum Computing (IQC) have demonstrated a new method, called cycle benchmarking, to assess scalability and compare capabilities of different quantum computer platforms. The finding leads the way towards establishing standards for quantum computing performance and strengthens the global effort to build a large-scale, practical quantum computer.
  • New twist in quest to develop understanding of time crystalline behavior November 21, 2019
    The quest to develop the understanding for time crystalline behaviour in quantum systems has taken a new, exciting twist.
  • The Unitary Fund Expands Into Its Next Phase with Additional Support November 21, 2019
    The Unitary Fund was established in 2018 to provide small micro-grants of $2,000 to fund people who wanted to explore open source quantum software projects. Since then it has funded eleven different projects in ten countries resulting in several technical papers being published and has helped to launch one new quantum startup. They have just […]
  • A super-fast 'light switch' for future cars and computers November 20, 2019
    Switching light beams quickly is important in many technological applications. Researchers have now developed an 'electro-opto-mechanical' switch for light beams that is considerably smaller and faster than current models. This is relevant for applications such as self-driving cars and optical quantum technologies.
  • CQC, Xanadu Release New Software Versions for Improved Multi-Platform Support November 19, 2019
    Cambridge Quantum Computing (CQC) has released version 0.4 of pytket, a Python tool for interfacing to their t|ket> quantum programming tools. Key features of this version include improvements in circuit optimization and qubit routing as well as a consistent back-end interface to allow easy switch between different quantum computing platforms or simulators. Currently, t|ket> support […]
