The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

Power miniblock for high current POL converters 22.01.2008

International Rectifier has announced the iP1206, a new technical solution for the implementation of step-down synchronous converters used to power telecommunications and network equipment.

The IC is the latest addition to the iPOWIR family of power miniblocks containing all the passive components and semiconductors for realizing the power part of synchronous converters. Based on iPl206, it is possible to implement a single-phase converter with an output current of up to 30 A and a two-phase converter with two independent outputs for currents of 15 A each. Both options are based on anti-phase operation of the channels in order to reduce input voltage and current ripple. To achieve high bulk density, iPl206 uses a full-fledged PWM controller and an optimized power stage based on modern semiconductor devices.

Since the new chip contains all the semiconductor and passive components that are important in terms of conversion quality, only a few additional power passive components are required to create a high-quality converter. At the same time, the requirements for the qualification of the developer and the printed circuit board are significantly reduced.

The features of the iP1206PBF are a constant PWM frequency of 600 kHz in the channels, lossless current limiting, overvoltage and overtemperature protection, offset start mode, and output voltage tracking. The input voltage range is 7,5...14,5 V, the output voltage range is 0,8...5,5 V.
