A groundbreaking theory bridges quantum mechanics and general relativity by treating the spacetime metric as a quantum operator and introducing an entropy-based gravitational action that yields modified Einstein equations with an emergent cosmological constant, potentially explaining cosmic expansion and dark matter through a novel auxiliary “G-field.”
Princeton physicists accidentally discovered and directly visualized Hofstadter’s butterfly—a theoretical fractal pattern of electron energy levels predicted in 1976—using scanning tunneling microscopy on twisted bilayer graphene, revealing not only the long-sought fractal energy spectrum but also new quantum phenomena driven by electron interactions beyond Hofstadter’s original calculations.
Recent experiments with superconductor-quantum dot hybrids demonstrate that contact-induced level broadening and hybridization effects in thermoelectric Cooper pair splitters lead to shifted resonances and parity reversal in thermoelectric current, revealing new avenues for harnessing nonlocal quantum correlations in solid-state systems through gate voltage control.
Quantum walks represent a revolutionary quantum computing paradigm that surpasses classical computational methods by leveraging fundamental quantum phenomena like superposition, interference, and entanglement. This technology has been comprehensively analyzed in recent research from China’s National […]
The ARQ19 patent’s claim of achieving long-range quantum key distribution without trusted nodes is unfounded because it relies on an unexplained confidential classical channel between end users that cannot be quantum-based due to distance limitations, making the system’s security ultimately dependent on this non-quantum channel rather than achieving true quantum security.
Scientists have presented a contraction strategy that makes use of the exact light cone structure of the tensor network representing the observables.
