Special Issue Information

Dear Colleagues,

The growing market of battery-operated portable electronic devices, wearable medical devices, and the wide application of the Internet of Things (IoT) in domestic life, the healthcare sector, manufacturing, and several other fields forced electronic circuit designers to become aware of energy efficiency and system management costs. These concerns are essential in modern electronics, allowing for lower device energy consumption and longer battery life or even proposed battery-less solutions.

The number of connected devices in IoT applications is expected to exceed 40 billion in 2025. Thus, it is vital to tackle the challenges involved in the design of ultra-low power solutions to ensure the feasibility of current and future systems, as well as to propose new mechanisms and energy extraction circuits that can complement or even replace the use of batteries. To achieve these goals, it is necessary to use special techniques to design low-power analog/digital integrated circuits.

For this Special Issue, authors are encouraged to submit their original research on the use of low-power integrated circuits to improve the energy efficiency of systems. Topics of interest include, but are not limited to, the following fields:

  • Novel energy harvesters;
  • Novel power management techniques and circuits;
  • Low-power sensor interfaces;
  • Low-power analog and mixed-signal circuits.

The implementation of quantum gates by means of microwave cryo-RFICs controlling qubits is a promising path toward scalable quantum processors. Quantum gate fidelity quantifies how well an actual quantum gate produces a quantum state close to the desired ideal one. Regrettably, the literature usually reports on quantum gate fidelity in a highly theoretical way, making it hard for RFIC designers to understand. This paper explains quantum gate fidelity by moving from Shannon’s concept of fidelity and proposing a detailed mathematical proof of a valuable integral formulation of quantum gate fidelity. Shannon’s information theory and the simple mathematics adopted for the proof are both expected to be in the background of electronics engineers. By using Shannon’s fidelity, this paper rationalizes the integral formulation of quantum gate fidelity. Because of the simple mathematics adopted, this paper also demystifies to electronics engineers how this integral formulation can be reduced to a more practical algebraic product matrix. This paper makes evident the practical utility of this matrix formulation by applying it to the specific examples of one- and two-qubit quantum gates. Moreover, this paper also compares mixed states, entanglement fidelity, and the error rate’s upper bound. Full article
