Pasqal reported strong H1 2026 financial results with €312.9M post-SPAC cash and 14% revenue growth. The company achieved significant technological breakthroughs, including scaling to 1,024 atoms and demonstrating logical qubit execution. Pasqal also expanded commercially with new deployments in Saudi Arabia and Italy, and became an XPRIZE finalist.

Sebastian Hassinger (The New Quantum Era): why neutral atoms lead the qubit race for nowTier 2

Yuval Boger interviews Sebastian Hassinger, host of The New Quantum Era podcast, and author of a new book by the same name. Sebastian and I have many things in common beyond our jobs in quantum. We are both podcasters, neither of us has a PhD, and we are both authors of new books – Sebastian’s […]

MANA Reveals Atomic-Scale Rails for Guiding Superconducting VorticesTier 2

Insider Brief PRESS RELEASE — Researchers at the Research Center for Materials Nanoarchitectonics (MANA), one of the centers under the National Institute for Materials Science (NIMS), Japan, discovered that atomic-scale steps can guide superconducting vortices in an ultrathin superconductor. Vortices moved more than 1,000 times more easily along the steps than across t...

Representation-Dependent Recoverability in Quantum CompilationTier 3

Fault-tolerant compilation can disperse high-level structure: schedules split an accumulated phase across rounds, gate synthesis replaces an angle by a Clifford+T word, and randomized compiling spreads rotations over sign-randomized fragments. They preserve the computation but change how cheaply a downstream compiler can recover the aggregate phase data. We formalize this...

Variational Multi-Gaussian Quantum TrajectoriesTier 3

We propose a variational framework for the efficient simulation of stochastic quantum dynamics in interacting bosonic systems. Our method generalizes the time-dependent variational principle to accommodate quantum state diffusion processes and is tailored for describing quantum trajectories unraveled from a master equation. We adopt a wavefunction ansatz composed of a cohere...

Disorder-induced quantum Fisher information in topological quantum systemsTier 3

The topological order of the Kitaev toric code is insensitive to disorder in its couplings since all star and plaquette operators commute; consequently, the stabilizer ground-state manifold is independent of the individual coupling strengths, and the phase remains stable against weak local perturbations. This insensitivity, however, is a property of the eigenstates and not o...

Transport and Channel Normal Forms for Clifford InteractionsTier 3

We study how Clifford interactions with a fixed environment determine quantum transmission, in a setting that extends positive discrete quantum convolution . We characterize when Clifford operations on the environment can be replaced by operations on the signal input and the two outputs, and classify the interactions under local Clifford transformations . For pure stabilizer...

The Uncertainty Principle, Uncertainty Relations, and Underlying Trajectories: Feynman, Nelson, Bohm, and Persistent Kac-Dirac DynamicsTier 3

A distinction should be made between quantum uncertainty relations and the broader uncertainty principle. The former are precise statistical consequences of quantum mechanics; the latter, when interpreted as excluding simultaneously definite conjugate variables and particle trajectories, is an additional ontological claim not implied by the uncertainty relations themselves....

Nonorthogonal variational quantum simulation for quantum chemistryTier 3

Dynamical simulation of quantum many-body systems is a central task in quantum chemistry and requires efficient wavefunction representations. Although tensor-network and neural-network quantum states have achieved considerable success in ground-state calculations, entanglement growth hinders their application to quantum dynamics. Quantum computing may offer a route to quantu...

The regularized channel Rényi divergence is continuousTier 3

We show that the regularized channel Rényi divergence is continuous at α= 1. As consequences, we establish an exponentially strong converse for channel discrimination, a subchannel-smoothed asymptotic equipartition property, a relative entropy accumulation theorem, and a new proof of the generalized quantum Stein's lemma. Our result further shows that the regularized chann...

Mphasis and Copa Airlines Host Quantum Computing Challenge for Airline OptimizationTier 2

Insider Brief PRESS RELEASE — Mphasis, (BSE: 526299; NSE: MPHASIS), a global AI-led, platform-driven technology solutions provider, in partnership with Copa Airlines, recently hosted a Quantum Computing Challenge, an international innovation contest. The challenge brought together teams from various Indian Institutes of Technology (IITs) in India and the University of...

Guest Post: Quantum Investment May Start With Post-Quantum SecurityTier 2

Guest Post By Courtney Olujobi, Principal at Moon Pursuit Capital. From an investment perspective, one of the first significant markets created by quantum computing may have very little to do with buying access to quantum computers themselves. It may come from the amount of capital businesses will need to spend protecting the financial systems, digital […]

ETSI Identifies Technical Limitations and Implementation Vulnerabilities in Quantum Random Number Generators (ETSI TR 104 171)Tier 2

ETSI's new report, TR 104 171, addresses vulnerabilities in Quantum Random Number Generators (QRNGs) due to practical hardware limitations. It provides guidelines across the QRNG lifecycle, including the Entropy Zero Trust (EZT) framework to mitigate side-channel attacks. The report also sets priorities for future standardization, such as API command sets and integration...
