'A. Sammak' 'M. Rispler' 'B. M. Terhal' 'Giordano Scappucci' 'M. Veldhorst'] The fault-tolerant operation of logical qubits is an important requirement for realizing a universal quantum computer. Spin qubits based on quantum dots have great potential to be scaled to large numbers because of their compatibility with…

permutations Authors: ['Ammar Daskin'] In this paper, we consider matrices given as a linear combination of permutations and analyze the impact of bit and phase flips on the perturbation of the eigenvalues. When the coefficients in the linear combination are positive, we observe that the eigenvalues of the resulting…

Quantum error correction is a key challenge for the development of practical quantum computers, a direction in which significant experimental progress has been made in recent years. In solid-state qubits, one of the leading information loss mechanisms is dephasing, usually modelled by phase flip errors. Here, we…

Modern statistical phasing methods efficiently and accurately infer haplotype phase in large genomic samples, and their performance is critical for downstream analyses. However, rigorously evaluating phasing accuracy remains challenging. Here we demonstrate the use of synthetic diploids generated from male X chromosome…

Modern statistical phasing methods have evolved to efficiently and more accurately infer the phase of haplotypes in large samples. However, these methods introduce errors that can impact downstream analyses. Here we employ both synthetic diploids generated from male X chromosome sequences and Mendelian-resolved trio…

'Ryan J. Marshman' 'Osamu Hirota'] The choice between the Schrödinger and Heisenberg pictures can significantly impact the computational resources needed to solve a problem, even though they are equivalent formulations of quantum mechanics. Here, we present a method for analysing Bosonic quantum circuits based on the…

Haplotypes can be estimated from unphased genotype data using statistical methods. When parent-offspring data are available for inferring true phase from Mendelian inheritance rules, the accuracy of statistical phasing is usually measured by the switch error rate, which is the proportion of pairs of consecutive…

'Andrea Melloni' 'Francesco Morichetti' 'David A. B. Miller' 'Olav Solgaard'] Optical phase measurement is critical for many applications and traditional approaches often suffer from mechanical instability, temporal latency, and computational complexity. In this paper, we describe compact phase sensor arrays based on…

To develop a Field-Correcting GRAPPA (FCG) technique to correct the spatiotemporal-varying phase errors in EPI caused by eddy currents. The fast-changing gradient in EPI causes strong eddy current effects and associated spatiotemporal-varying phase errors, producing significant image artifacts. The use of higher…

Multiple wavelength phase shifting interferometry is widely used to extend the unambiguous range (UR) beyond that of a single wavelength. Towards this end, many algorithms have been developed to calculate the optical path difference (OPD) from the phase measurements of multiple wavelengths. These algorithms fail when…

In this work, we present a new approach to retrieve the optical phase map of an object which is projected by a single differentiated two-beam interference pattern. This approach is based on the differentiation of the intensity equation of the two-beam interference with respect to the carrier’s phase angle. Therefore…

projection system Authors: ['Sanghoon Jeon' 'H. J. Lee' 'Jaesung Lee' 'B.H. Kang' 'Byung-Wook Jeon' 'Jun Young Yoon' 'Jae‐Sang Hyun'] In phase-shifting profilometry (PSP), any motion during the acquisition of fringe patterns can introduce errors because it assumes both the object and measurement system are stationary.…

A rapid phase symmetry method for finding the center of rotation in tomographic data using two images located 180° ± Δθ apart is introduced. The method is more robust against photon noise than image correlation methods, and shows good tolerance to Δθ ranging up to several degrees.

'Shouhuan Zhou' 'Zeyu Ma' 'Wenwu Wang' 'Liang He'] An improved three-frequency heterodyne synthesis phase unwrapping method is proposed to improve the measurement accuracy through phase difference and phase sum operations. This method can reduce the effect of noise and increase the equivalent phase frequency. According…

Quantum Memories Authors: ['Tzu‐Yung Huang' 'David A. Hopper' 'Kaisarbek Omirzakhov' 'Mohamad Hossein Idjadi' 'S. Alexander Breitweiser' 'Firooz Aflatouni' 'Lee C. Bassett'] As quantum networks expand and are deployed outside research laboratories, a need arises to design and integrate compact control electronics for…

Hyperspectral imaging (HSI) is a paramount technique in biomedical science, however, unmixing and quantification of each spectral component is a challenging task. Traditional unmixing relies on algorithms that need spectroscopic parameters from the fluorescent species in the sample. The phasor-based multi-harmonic…

'Wojciech Zwolinski' 'Radosław Chrapkiewicz' 'Mayukh Lahiri' 'Radek Lapkiewicz'] Interferometric methods form the basis of highly sensitive measurement techniques from astronomy to bioimaging. Interferometry typically requires high stability between the measured and reference beams. The presence of rapid phase…

The simultaneous and independent measurement of multiple movement forms is a significant issue to be solved in research. In this paper, we proposed a method that combines the self-interference of conjugated optical vortices and external interference of plane waves, and successfully realize the independent measurement…
