Can error correction in a quantum computer actually fail even when it appears to be working perfectly. New theoretical work reveals that imperfect decoding strategies can enter a previously unknown “t…

Scalable quantum interference has moved beyond paired emitters for the first time. Previously restricted to two independent quantum dots, this work demonstrates controlled interference from five such …

Previously, calculating how quantum systems interact with their surroundings was expected to become exponentially more difficult as simulation time increased. Now, calculations for many realistic scen…

Until now, analytical solutions for these complex two-matrix models extended only to specific instances like the ABAB configuration. Monte Carlo simulations now offer a means to map the critical curve…

Previously, identifying the boundary between order and chaos in quantum systems relied on indirect measures of internal state. Now, the extent to which a quantum state explores its possible configurat…

For years, creating complex quantum states demanded exhaustive searches of possibilities, a process quickly overwhelmed by even modest system sizes. Now, a new method exploits the underlying structure…

Cleveland Clinic and IBM researchers have demonstrated a quantum workflow for simulating the electronic structure of a protein, a task becoming increasingly difficult for traditional computers as mole…

Simulations of quantum materials with up to 1000 qubits are now within reach, thanks to a new approach to controlling quantum systems. Previously limited by the computational cost of manipulating comp…

Within a loop of nonlinear waveguides, entanglement blossomed for any number divisible by four, a constraint previously unseen in theoretical models. Until now, simulating multipartite entanglement in…

A scaling of ε 1/3 , observed in third-order exceptional points within parity-time-symmetric systems, reveals a previously hidden link between symmetry and the strength of these critical singularities…

Until now, optimising quantum repeater networks meant choosing between fastest delivery or complex, real-time calculations. A new routing scheme bypasses this trade-off by randomly distributing entang…

Researchers Map How Quantum Computing Could Accelerate Single-Cell Biology The Quantum Insider

Until now, the Quantum Computing Quantum Monte Carlo framework largely confined itself to calculating a system’s lowest energy state. This work systematically builds quantum circuits to unlock a far b…

Previously, determining the thermal behaviour of even moderately sized quantum systems demanded computational power that grew exponentially with complexity. Now, a new algorithm, the Quantum Finite Te…

Quantum mining of Bitcoin demands a fleet of qubits equivalent to a large national grid. Calculations reveal that achieving a practical advantage requires approximately 10^8 physical qubits and 10^4 m…

Until now, the systematic application of established mathematical tools to address errors in quantum computation has been largely absent. Previously hampered by rapid hardware development and conceptu…

planqc recently hired Eda Sorani as a Business Development Specialist, bringing expertise in theoretical physics and quantum information science to the company. Sorani will focus on bridging the gap b…

Beijing University of Posts and Telecommunications researchers propose a quantum multiview kernel learning approach, L-QMVKL, to address performance limitations in complex data by fusing information a…

Previously, verifying quantum circuits meant accepting a degree of uncertainty in the final result. Now, a new method precisely tracks even subtle global phases, opening equivalence checking to circui…

Previously hampered by a lack of demonstrable advantage, quantum machine learning may find purchase through spectral methods. Manipulating the Fourier spectrum of complex models is computationally exp…

Within a lattice of interacting qubits, persistent quantum correlations have been observed even as entanglement fades. Previously, detecting these correlations necessitated strong entanglement, but th…

Until recently, securing 5G connections via Wi-Fi and other non-3GPP access points depended on encryption vulnerable to future quantum computers. Now, a functional system integrates Quantum Key Distri…

Xanadu Quantum Technologies Limited has become a publicly listed company, beginning trading on both the Nasdaq and Toronto Stock Exchange under the symbol "XNDU." The listing follows a business combin…

IBM’s quantum computer accurately simulated magnetic materials, matching data from neutron scattering experiments at Oak Ridge National Laboratory. This advance demonstrates the potential of quantum-c…
