Quantum Bitcoin Mining Requires Astronomical Resources, Study Finds 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 megawatts of power, even for a limited attack. Scaling this to current Bitcoin difficulty elevates the requirement to 10^23 qubits and an energy consumption nearing a Kardashev Type II civilisation.

Engineered Lattices Stabilise Exotic Chiral Spin Liquid State For years, definitive evidence of quantum spin liquids, materials behaving as though their magnetic moments are perpetually disordered, has remained elusive. Now, calculations reveal a chiral spin liquid stabilised through precisely arranged interactions within an artificial lattice of spin-1/2 particles. This work proposes how arrays of Rydberg atoms or polar molecules could directly observe this exotic state, bypassing the challenges of finding it in conventional materials.

Quantum Computers Gain Accuracy With Far Fewer Measurements Needed Could accurate results ever be salvaged from quantum computations too complex for existing error correction methods. MoSAIC achieves this by reducing the sampling costs of probabilistic error cancellation, enabling mitigation of circuits previously considered intractable. Experiments on IBM’s 156-qubit Heron processor demonstrate at least a ten-fold improvement in accuracy for larger quantum systems.

Quantum Simulations Now Accurately Model Molecular Behaviour At Low Temperatures Previously, molecular simulations routinely overlooked a subtle quantum effect linked to molecular shape and reactivity. Now, a refined computational method inherently accounts for this geometric phase, promising more accurate predictions of molecular behaviour at low temperatures. This advance corrects a long-standing omission in standard simulations, particularly where molecules undergo rapid changes in electronic state.

Faster Quantum Checks Use Standard Computers To Verify Entanglement Until now, verifying quantum entanglement demanded collecting every measurement before analysis could begin. This work shifts that process, enabling real-time detection during the quantum experiment itself. By processing data as it arrives, rather than afterwards, fewer samples are needed to confirm entanglement, opening possibilities for more complex computations on noisy intermediate-scale quantum devices.

Atomic Clocks Become More Accurate With New Light Shift Cancellation Previously, building dependable atomic clocks meant painstakingly seeking ‘magic wavelengths’ of light or devising workarounds specific to each atomic species. Now, a new technique cancels out disruptive light shifts directly within the clock itself, irrespective of the atoms used or the light’s colour. This in-situ cancellation offers a broadly applicable path towards more stable and accurate timekeeping devices and quantum sensors.

Quantum Particles Bypass ‘self-Trapping’ With New Simulation Technique Two particles, seemingly held fast by an invisible barrier, can now be accurately modelled as they tunnel through it, a feat previously hampered by a persistent distortion in calculations. The time-dependent generator coordinate method overcomes this ‘self-trapping’ effect, aligning simulated quantum tunneling with known exact solutions. This advance promises more reliable modelling of nuclear reactions and fission processes.

Quantum Networks Now Route Entanglement Through Complex Real-World Systems Entanglement distribution now bypasses distance limitations within square grid networks, achieving higher rates than conventional methods. This improvement stems from a new hybrid routing strategy combining Greenberger-Horne-Zeilinger (GHZ) measurements with standard Bell state measurements. However, realising these gains in more complex network topologies demands further refinement and complete network awareness.
