A recipe transforms any GHZ-preparing CNOT block into a fanout gate at twice the depth. Applied to IBM's ibm_fez heavy-hex topology, this yields a 156-qubit fanout (depth 33) enabling single-shot full characterization of 156-qubit GHZ states.

LQAS, an evolution-inspired heuristic, automates PQC design via localized gate modifications. Tested on synthetic & quantum chemistry datasets, it boosted R² from -0.993 to 0.958 and was deployed on IBM 156-qubit Heron r2 processors.

Kissinger & van de Wetering introduce ZX-flow, a new flow criterion native to ZX-diagrams using Pauli semiwebs, enabling Clifford-rewrite-stable circuit extraction and equivalence to Pauli flow up to Clifford rewrites.

New Clifford+Toffoli circuits achieve Θ(n) gates and Θ(log n) depth for comparators and incrementers with provably minimal qubits, improving Shor's algorithm depth from O(n³) to O(n² log² n) via a novel 'promise gate' framework.

SRBB-based QNN achieves exponential CNOT reduction via single-layer approximation for unitary synthesis. Validated on sparse/dense matrices up to 6 qubits with PennyLane and IBM quantum hardware, benchmarked against existing decomposition methods.
#UnitarySynthesis #QuantumCircuits #News
Researchers propose a beam search heuristic for distributed quantum circuit partitioning, achieving lower communication costs than METIS with O(N²T) complexity—outperforming metaheuristics while adapting to arbitrary QPU network topologies.
