SYSTEM AND METHOD OF CARRIER-FREE RAMAN TRANSITION FOR ENTANGLEMENT GENERATION WITH TRAPPED IONS

Resumen de: US20260244970A1

Technologies for generating entanglement in a quantum computing system include confining ions in trapping potentials that define at least one shared motional mode. First and second electromagnetic fields are generated and combined to form a Raman interaction field having a frequency difference corresponding to an internal state transition of the ions. At least one of the electromagnetic fields is spatially structured to produce an electric-field null and a transverse spatial gradient. The Raman interaction field is directed toward the ions such that at least one ion is positioned at the electric-field null. Application of the Raman interaction field induces coupling between internal states of the ions and the shared motional mode while suppressing carrier transitions by the spatial field structure. Coupling of internal states of multiple ions to the shared motional mode mediates entanglement between the ions.

ERROR MITIGATION FOR QUANTUM COMPUTING

Resumen de: WO2026173562A2

One example aspect of the present disclosure is directed to a method for operating a quantum computing system (QCS) that includes a set of qubits. The method includes generating a set of noisy data by repeatably measuring a noisy observable of a quantum circuit operating on the set of qubits. The set of noisy data and the noisy observable are subject to noise associated with the quantum circuit and each datapoint of the set of noisy data is associated with an eigenvalue of the noisy observable. The noisy data is modeled as a hybrid distribution, which includes a combination of a noiseless distribution and a noise-only distribution. Each datapoint of the set of noisy data is assumed to have a hidden label as coming from either the noiseless distribution or the noise-only distribution. This label is estimated for each datapoint, based on the eigenvalue associated with the datapoint, and a constructed model for any of the hybrid distribution, the noise-only distribution, and the noiseless distribution. This may require additional data to be taken from the QCS to model the noise-only distribution. A target quantity is determined based on either the model for the noiseless distribution or the datapoints combined with their attached labels.

METHODS AND SYSTEMS FOR IMPLEMENTING SHOR'S ALGORITHM WITH QUDIT RECYCLING

Resumen de: US20260244972A1

0000 Quantum computing harnesses harness quantum mechanics to solve a range of problems extending beyond the capabilities of electronic computers. Quantum computing exploits superposition, entanglement, coherence and interference where quantum processors combine qubits to store information and perform algorithms to yield computational outcomes. One such algorithm is Shor's algorithm which enables superpolynomial speedup in factoring large integers as it can explore multiple potential solutions simultaneously rather than sequentially. However, Shor's algorithm requires the substantial computational resources, qubits, to achieve optimal precision in determining factorization solutions, even for relatively small numbers. To address an approach is presented exploiting higher-dimensional quantum units (qudits) with optimization of the dimensionality of qudits to minimize the number of recycling steps in the iterative Shor's algorithm allowing smaller circuit depths, thereby reducing circuit complexity with deterministic entangling operations to enhance circuit efficiency by utilizing two distinct photonic degrees of freedom.
