Performance Benchmark Comparison versus QuTip for Five Different Cases on both CPU and GPU based Systems. Credit: Alice & Bob Alice & Bob has introduced Dynamiqs, an open-source quantum simulation Python library that integrates NVIDIA-accelerated computing to achieve up to 60x faster performance in quantum simulations. Developed in collaboration with researchers from institutions including the University of Sherbrooke, Yale, INRIA, Ecole de Mines, and ENS, Dynamiqs addresses the computational challenges of simulating complex quantum systems, enabling breakthroughs in quantum research and development. The library leverages NVIDIA GPU acceleration and the differentiability of JAX and Diffrax frameworks to enhance simulation capabilities. GPU [...]

EDF, in partnership with Quandela, Alice & Bob, and CNRS, has embarked on a groundbreaking €6.1 million ($6.542M USD) project named "Energy Optimization of Quantum Circuits" (OECQ), supported with a grant of up to €4.5 million ($4.87M USD) from France 2030 through Bpifrance. The primary objective of OECQ is to evaluate and enhance the energy efficiency of quantum computing systems in comparison to traditional high-performance computing (HPC) methods. This initiative represents a critical milestone in quantifying the energy requirements of quantum processors across real-world applications such as optimization, physical simulation, and material science. EDF, a leader in energy solutions, will provide energy-intensive [...]

Ben Bloom has been named interim CEO of Atom Computing succeeding Rob Hays who has left the company. Dr. Bloom founded the company in 2018 and served as its initial CEO. He has been the CTO since 2021. Before Atom Computing, he has previous experience at Rigetti Computing, Intel, and JILA where he helped to build the first Optical Lattice Clock. An updated web page showing the company's current executive leadership has been posted on the company's website here. Charles Tahan has joined Microsoft Quantum where he will be leading a technical team in the Washington, DC metropolitan area. Previously, Dr. [...]

Riverlane, a global leader in quantum error correction technology, and Alice & Bob, a developer of fault-tolerant quantum computers, have signed a collaboration agreement to integrate Riverlane’s quantum error correction (QEC) stack with Alice & Bob's cat qubit technology. Cat qubits, a unique type of superconducting qubit developed by Alice & Bob, are designed to reduce bit-flip errors, addressing a key challenge in quantum computing. Quantum computers require error correction to address both bit and phase flip errors in real-time. Riverlane’s QEC stack, Deltaflow, incorporates a powerful quantum error decoder, which complements the error resistance of cat qubits. This integration aims [...]

Die Photo of Boson 4. Credit: Alice & Bob We have previously published many articles about the cat qubit technology being developed by Alice & Bob. Their approach to combat qubit errors is different from what other companies are pursuing. In a quantum computer there are two basic types of errors that can occur, bit-flips and phase-flips. So conventional quantum error codes, like the surface code, need to be design to correct both types of errors. In the Alice & Bob architecture, the bit flips are nearly eliminated by the hardware architecture that they use so that their error codes only [...]

Alice & Bob, a quantum hardware manufacturer, is collaborating with NVIDIA to integrate cat qubits into future datacenters. Leveraging NVIDIA technology such as DGX Quantum and CUDA Quantum, this integration aims to advance quantum computing alongside classical computing methods. DGX Quantum combines NVIDIA GH200 Grace Hopper Superchips and the Quantum Machines’ OPX+ control system to provide quantum error correction, calibration, control and processing of hybrid algorithms at high performance. Cat qubits, known for their passive error correction, represent a promising platform for fault-tolerant quantum computing. Through partnerships and innovations like DYNAMIQS, an open-source quantum systems simulation library that is accelerated by GPUs and developed by [...]
