Summary: This paper examines the concept of quantum probability within quantum computation and logic, discussing both subjectivist and objectivist interpretations. It proposes an objectivist interpretation based on the idea that the Born rule provides information about an intensive realm of reality, and explores the implications for modeling and development in quantum computation and quantum computational logic.

Summary: The problem of testing two hypotheses of quantum operations with an arbitrary prior probability distribution in a setting of many uses is considered. The Chernoff exponent for quantum operations is investigated to track the minimal average error probability of discriminating two quantum operations asymptotically. It is shown that the Chernoff exponent is finite if and only if the quantum operations can not be perfectly distinguished with finite uses, ruling out the possibility of super-exponential decay of error probability. Upper bounds of the Chernoff exponent for quantum operations are provided.

Summary: Careful study of entangled qubits on the IBM Rochester revealed a scaling property that protects them from environmental noise. Most measurements were reproducible within a short gate operation time, but some combinations of qubits showed significant entanglement evolution. The analysis further delved into the phase trajectory of entangled evolution, as well as the impact of the sudden death of GHZ-like states and the emergence of newly excited states on a noisy intermediate-scale quantum (NISQ) computer.

Summary: This work presents priori error estimates for local reliability-based sensitivity analysis using the Score Function Method and Weak Approach with Monte Carlo Simulation. The results are crucial for practical parameter selection in local sensitivity analysis, and can also be utilized for future development of a posteriori error estimates and adaptive schemes. The theoretical results, initially obtained for the one dimensional case, are also applicable in multidimensional contexts, as evidenced by numerical experiments.

Summary: There is an acknowledgement that maritime cybersecurity risk management should consider process, technology, and people. However, most studies have focused on technical and process aspects, rather than the human element. This study aims to identify the responsibilities of navigating officers for ECDIS cybersecurity and analyze human error probabilities, providing insights for industrial policies and best practices in ECDIS cybersecurity risk management.

Summary: This study decomposes two implementations of Shor's algorithm for prime factorization into universal gate units at the logical level and predicts the number of physical qubits and execution time when surface codes are used. Assuming logical qubit encoding using a rotated surface code and logical qubits with all-to-all connectivity, the number of physical qubits and execution time are expressed in terms of the bit length of the number to be factorized and error rate of the physical quantum gate. By analyzing two algorithms with different bit lengths and physical gate error rates, the relationship between the number of qubits and the execution time is confirmed.

Summary: A simulator specifically designed for photonic quantum information processing (PQIP) experiments is urgently needed due to the unique characteristics of PQIP experiments. PhotoniQLAB, an object-oriented framework, was developed to provide a virtual-lab user experience, allowing users to conduct simulations by entering target experiment structure information. The performance and versatility of PhotoniQLAB have been demonstrated through simulating over 60 existing PQIP experiments.

Summary: This study investigates the effect of tool attitude error on the taper angle error of steep taper wire-cut electrical discharge machines (EDM) and establishes a mathematical model. The research finds that positioning error is the major factor contributing to the attitude error. A comparison experiment shows that reducing positioning error effectively decreases the volumetric attitude error.

Summary: This paper proposes an FTQC architecture called Q3DE, which enhances the tolerance to multi-bit burst errors (MBBEs) caused by cosmic rays. Through dynamic adjustments of the encoding level and re-estimating recovery operations, Q3DE effectively reduces the impact of MBBEs and decreases their period and size. This scheme is versatile for various physical devices and FTQC architectures.

Summary: Quantum tomography is a commonly used characterization method in experiments, but its standard protocols are unreliable due to preknowledge assumptions. Self-consistent quantum tomography treats each quantum operation as an unknown object to be characterized, but faces the challenge of unique determination of characterization results due to experimentally undetectable gauge degrees of freedom. Regularization technique is proposed to fix the gauge with a method that converges to the quantum operations' gauge-equivalence class at the limit of infinite data, ensuring reliability.
