Quantum 10, 2039 (2026). https://doi.org/10.22331/q-2026-03-23-2039 Given an algorithm that outputs the correct answer with bounded error, say $1/3$, it is sometimes desirable to reduce this error to some arbitrarily small $varepsilon$ – e.g., if one […]
Insider Brief A new study proposes “quantum telepathy,” a method that uses entanglement to coordinate decisions between systems when real-time communication is limited. Beyond high-frequency trading, the researchers outline broader applications including load balancing in […]
Insider Brief Q*Bird and the Walton Institute at SETU deployed Ireland’s first multi-node, entanglement-based MDI-QKD network over existing fiber, marking a shift from research to operational national quantum-secure infrastructure within the IrelandQCI and EuroQCI frameworks. […]

Quantum 10, 2038 (2026). https://doi.org/10.22331/q-2026-03-23-2038 Quantum walks in general graphs, or more specifically scattering on graphs, encompass enough complexity to perform universal quantum computation. Any given quantum circuit can be broken down into single- and […]
Quantum 10, 2037 (2026). https://doi.org/10.22331/q-2026-03-23-2037 In recent years, quantum key distribution (QKD) has evolved from a scientific research field to a commercially available security solution, supported by mathematically formulated security proofs. However, since the knowledge […]
Insider Brief A German-led research project called QIAPO is developing a hybrid quantum-classical approach to improve solutions to complex optimization problems such as logistics and manufacturing, where classical methods remain limited. The method uses neutral […]
Quantum 10, 2036 (2026). https://doi.org/10.22331/q-2026-03-23-2036 We introduce an efficient method to quantify nonstabilizerness in fermionic Gaussian states, overcoming the long-standing challenge posed by their extensive entanglement. Using a perfect sampling scheme based on an underlying […]
Scientists in Australia have demonstrated a prototype quantum battery that could revolutionize energy storage. By harnessing quantum effects, it can absorb energy in a rapid “super absorption” event, enabling much faster charging than conventional batteries. […]
