ColdQuanta Could Become the Fastest Scaling Quantum Computer Approach

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. …

Solving 10,000 Year Google Quantum Problem in 5 Days Using 60 GPUs

60 graphical processing units (GPUs) have been used to solve the Google quantum supremacy computer problem. Researchers generated one million correlated bitstrings with some entries fixed, from the Sycamore circuit with 53 qubits and 20 cycles, with linear cross-entropy benchmark (XEB) fidelity equals 0.739, which is much higher than those in Google’s quantum supremacy experiment. …

New Passive Quantum Error Correction Could Be The Breakthrough for Large Scale Quantum Computers

Researchers led by Prof. David DiVincenzo from Forschungszentrum Jülich and RWTH Aachen University, and partners from the University of Basel and QuTech Delft, have now proposed a design for a quantum computer circuit with passive error correction. Such a circuit would already be inherently fault protected and could significantly accelerate the construction of a quantum …

Path to Large Scale Qubits and Super Quantum Computers

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 Comments on the Boson Sampling Quantum Supremacy Paper from China

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 …
