Researchers Cut Overhead in Quantum Error Assessment
Reducing assessment time for complex quantum circuits has long been limited by the escalating demands on experimental resources. Now, a new method cuts those requirements by partitioning operator pairs, allowing multiple measurements with fewer settings than previously possible. This approach offers an unbiased technique that guarantees reductions in input/output configurations, paving the way towards scalable fault tolerance.
Semiconductor leader John Hollister joins Silicon Quantum Computing as CFO
Silicon Quantum Computing announced the appointment of John Hollister as Chief Financial Officer, effective 17 August 2026. Hollister brings 25+ years of financial leadership across the global semiconductor industry, including previous CFO roles at GlobalFoundries and Silicon Labs.
Fortaegis Technologies Raises $50 Million Series A to Deploy Hardware-Rooted Quantum-Safe Secure Compute Architecture
Fortaegis Technologies has successfully closed a $50 million Series A funding round led by Serendipity Capital, with participation from major strategic investors. This capital will accelerate the deployment of their hardware-rooted quantum-safe secure compute architecture, which provides advanced security against AI and post-quantum decryption threats by generating dynamic, quantum-resistant encryption keys from physical silicon properties. The company plans to scale FPGA deployment and devel...
University of Pennsylvania Demonstrates Single-Gate Parallel Entanglement on Room-Temperature Diamond Quantum Register
University of Pennsylvania researchers have achieved a breakthrough in quantum computing by demonstrating single-gate, parallelized multipartite entanglement on a room-temperature diamond quantum register. They successfully generated a four-qubit Greenberger–Horne–Zeilinger (GHZ) state in just 14.8 microseconds, a tenfold speedup over traditional methods, with significantly improved fidelity. This new approach, detailed in Nature Nanotechnology, converts inherent crosstalk into parallel condi...
IBM Research Demonstrates Hybrid Spacetime PEC to Reduce Error-Mitigation Sampling Overhead by 63×
IBM Research has introduced Spacetime Probabilistic Error Cancellation (Spacetime PEC), a hybrid error-handling framework that significantly reduces the sampling overhead in quantum computing. This new protocol combines Probabilistic Error Cancellation (PEC) with post-selected Quantum Error Detection (ED), achieving up to a 63-fold reduction in sampling overhead compared to standard PEC. The approach was experimentally validated on IBM's 27-qubit heavy-hex superconducting processor, demonstra...
