Special Issue Information

Dear Colleagues,

The development of quantum devices for sensing and other applications is a new and exciting field of physics and engineering which includes technologies that utilize properties of quantum mechanics, such as quantum entanglement, quantum superposition, quantum interference, quantum tunneling, etc., to provide enhanced precision and performance compared to conventional approaches. These devices are expected to find important applications in a wide variety of fields, such as in sensors, quantum computing, imaging, quantum energy generators, space navigation, etc. Quantum sensors in particular could be utilized in many interesting areas, including microscopy, positioning systems, communication technology, electric and magnetic field sensing, etc. Within this new technology, individual quantum systems can be used as sensing elements to enhance sensitivity and boost the overall performance of conventional sensors through quantum effects such as entanglement, superposition, interference and squeezing. For example, a novel device has been proposed recently [1] that utilizes Weyl fermions to both control the flow of information across several channels simultaneously and sense electric fields with enhanced sensitivity and performance.

In this work we propose a novel device for controlling the flow of information using Weyl fermions. Based on a previous work by our group, we show that it is possible to fully control the flow of Weyl fermions on several different channels by applying an electric field perpendicular to the direction of motion of the particles on each channel. In this way, we can transmit information as logical bits, depending on the existence or not of a Weyl current on each channel. We also show that the response time of this device is exceptionally low, less than 1 ps, for typical values of its parameters, allowing for the control of the flow of information at extremely high rates of the order of 100 Petabits per second. Alternatively, this device could also operate as an electric field sensor. In addition, we demonstrate that Weyl fermions can be efficiently guided through the proposed device using appropriate magnetic fields. Finally, we discuss some particularly interesting remarks regarding the electromagnetic interactions of high-energy particles. Full article
