Loss Errors in Error-Corrected Circuits Across A Range Of Quantum Hardware Platforms (MIT, Harvard, QuEra)
By Technical Paper Link - 13 Jan, 2026 - Comments: 0

A new technical paper titled "Leveraging Qubit Loss Detection in Fault-Tolerant Quantum Algorithms" was published by researchers at MIT, Harvard and QuEra Computing. Abstract "Qubit loss errors constitute a dominant source of noise in many quantum hardware systems, particularly in neutral-atom quantum computers. We develop a theoretical framework to effectively detect and correct loss err... » read more

Quantum Computing: How Advances May Reshape Our Understanding Of The World
By Greg Sorber - 18 Sep, 2025 - Comments: 0

After decades spent gestating in labs, quantum computing has finally reached an inflection point between theoretical promise and practical implementation. From discoveries in pharmaceutical and material sciences to boosting artificial intelligence (AI) and climate modeling, quantum computing is on the cusp of providing an entirely new way to solve highly complex problems — which could ultimat... » read more

Materials Modeling Of Superconducting Qubits In Quantum Computers
By Anders Blom - 21 Aug, 2025 - Comments: 0

While the concept of quantum computing has been discussed for more than 40 years, only recently have experiments indicated that a practical quantum computer may be possible. Recent developments in this area have captured headlines with dramatic claims—and equally dramatic rebuttals. Google’s Willow chip demonstrated error-corrected operations in late 2024, while D-Wave’s assertion of quan... » read more

Quantum on silicon Researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) developed a platform to probe and control qubits in silicon for quantum networks, after an earlier discovery that defects in silicon could be used to send and store quantum information over widely used telecommunications wavelengths. The device uses an electric diode to manipulate... » read more

Ultra-pure silicon Researchers from the University of Manchester and University of Melbourne developed a technique to engineer ultra-pure silicon that could be used in the construction of high-performance qubit devices that extend quantum coherence times. The highly purified silicon chips house and protect the qubits so they can sustain quantum coherence much longer, enabling complex calcul... » read more

Quantum Computing Challenged By Security, Error Correction
By Karen Heyman - 04 Apr, 2024 - Comments: 0

The number and volume of warnings about a post-quantum cryptography (PQC) world are rising, as governments, banks, and other entities prepare for a rash of compromised data and untrustworthy digital signatures. Exactly when this will become a genuine threat is still somewhat fuzzy, because it depends on progress in developing robust qubits. A report by McKinsey & Co. estimates that by 20... » read more
