Xanadu Quantum Technologies is a Canadian quantum computing hardware and software with US$145 million of funding. In May, 2021, they raised US$100M in Series B financing. Bessemer Venture Partners led the round with participation from Capricorn, Tiger Global, BDC Capital, In-Q-Tel, along with returning investors Georgian, OMERS, and Tim Draper. The round brings Xanadu’s total …
Reservoir computing is an approach to make machine learning algorithms run faster. The word reservoir refers to a dynamical system. The reservoir consists of a bunch of recurrently connected units that are connected randomly. The main forms of reservoir computing use a recurrent neural network, and instead of updating all parameters of the network, it …
Nextbigfuture interviewed Tom Noel, ColdQuanta’s Director of Quantum Computing and Interim CEO Dan Caruso. ColdQuanta is using neutral atoms instead of trapped ions as the basis for its quantum computers. ColdQuanta is building a functional first system now and believes they will be able to scale to the 1000s of qubits faster than competing approaches. …
The technology that we long believed would characterize the future has not just gotten billions in investment but there are many companies with multi-billion valuations to transform the world to future technology. There are things like quantum computers and flying cars. Thirteen years ago in 2008, Nextbigfuture discussed a radically transformation of the world with …
IonQ trapped ion quantum computer is completing a $2 billion SPAC merger which will give it about $600 million in cash to fund its quantum computer developments. IonQ indicates that its 32 qubit trapped ion quantum computer can achieve a quantum volume of 4 million. Honeywell has the leading commercial quantum computer (also trapped ion) …
D-Wave Systems Inc., the leader in quantum computing systems, software, and services, today published a milestone study in collaboration with scientists at Google, demonstrating a computational performance advantage, increasing with both simulation size and problem hardness, to over 3 million times that of corresponding classical methods. Notably, this work was achieved on a practical application …
A European consortium was launched with the goal of scaling silicon quantum technologies. This will be a four-year 15 million euro projecte named QLSI (Quantum Large-Scale Integration with Silicon). It will be coordinated by CEA-Leti and will lay the foundation for the EU’s industrial-scale implementation of semiconductor quantum processors and position Europe as a global …
CEA-Leti scientists have opened a pathway to large-scale integration of Si-spin qubits using existing flip-chip processes with die-to-wafer 3D-interconnect technologies developed in-house. They determined electrical characterizations at cryogenic temperatures of chip assemblies made with 3D interconnects such as SnAg microbumps and direct Cu bonded pads from Cu/SiO2 hybrid bonding process. SnAg microbumps have the advantage …
Scott Aaronson originated the proposal of Boson Sampling as an area where quantum computers should be better than regular computers. He discusses the new claim from China of Quantum Supremacy where quantum computing systems are 10 trillion times faster than regular supercomputers on a particular problem. A group led by Jianwei Pan and Chao-Yang Lu …
Chinese researchers performed Gaussian boson sampling by sending 50 indistinguishable single-mode squeezed states into a 100-mode ultralow-loss interferometer with full connectivity and random matrix—the whole optical setup is phase-locked—and sampling the output using 100 high-efficiency single-photon detectors. The obtained samples are validated against plausible hypotheses exploiting thermal states, distinguishable photons, and uniform distribution. The photonic …
In 2019 at the QCWare Q2B conference, Phillip Gerbert, Senior Partner and Managing Director at BCG, and Matt Langione, Project Leader at BCG presented their estimation of the business market for quantum computers over the next 20 years. This assumes that it will take 20 years to reach large scale error corrected quantum computers. BCG …
