The Atomtronics@AbuDhabi2021 meeting, held virtually via Zoom, focused on recent advancements in cold atom quantum technology, particularly within the emerging field of Atomtronics. The meeting covered applicative, experimental, and theoretical aspects of atomic circuits for computation, communication, and sensing. Poster sessions were organized in Zoom breakout rooms. Why it matters: The event signals growing interest and activity in quantum technologies and quantum simulation within the UAE, with potential implications for future research and development in the region.
Researchers from LENS, CNR-INO, the University of Florence, UNAM, RPTU University Kaiserslautern-Landau, and TII Abu Dhabi have observed Shapiro steps in ultracold atoms for the first time. This allows for real-time observation of quantum mechanics and could lead to advanced quantum sensors and simulation. The experiments involved creating vortex-antivortex pairs, resulting in step-like signals, and the findings were published in Science. Why it matters: This breakthrough provides a new method to observe and control quantum coherence, potentially enabling advancements in quantum technologies and simulations within the region.
A KAUST team led by Hossein Fariborzi won second place in the MEMS Design Contest for their "MEMS Resonator for Oscillator, Tunable Filter and Re-Programmable Logic Applications." The device is runtime-reprogrammable, allowing the function of each device in the circuit to be changed during operation. The KAUST team demonstrated that two MEMS resonators could replace over 20 transistors in applications like digital adders, reducing digital circuit complexity. Why it matters: This innovation could significantly reduce power consumption, chip area, and manufacturing costs in microprocessors, advancing the development of energy-efficient microcomputers in the region.
KAUST researchers collaborated with TSMC to review the potential of 2D materials in overcoming silicon limitations for microchips. They find that while 2D materials show promise, performance degrades when using scalable fabrication techniques like chemical vapor deposition. 2D materials have been integrated into some commercial products like sensors, but high-integration-density circuits are still a challenge. Why it matters: This research highlights the ongoing efforts and remaining hurdles in utilizing novel materials to advance semiconductor technology in line with industry roadmaps.
Prof. Simon Gröblacher from Delft University of Technology presented a seminar on using mechanical systems in quantum information processing, focusing on their potential as quantum memories and transducers. The seminar highlighted experiments demonstrating non-classical behavior of mechanical motion by coupling a micro-fabricated acoustic resonator to single optical photons. Quantum control over acoustic motion was established, including the generation and readout of single phononic excitations, along with light-matter entanglement. Why it matters: This research advances the use of micro-fabricated acoustic resonators for quantum information processing and fundamental tests of quantum physics.
KAUST researchers have designed an integrated circuit logic lock to protect electronic devices from cyberattacks. The protective logic locks are based on spintronics and can be incorporated into electronic chips. The lock uses a magnetic tunnel junction (MTJ) where the keys are stored in tamper-proof memory, ensuring hardware security. Why it matters: This hardware-based security feature could significantly increase confidence in globalized integrated circuit manufacturing, protecting against counterfeiting and malicious modifications.
Prof. Luigi Amico of the Quantum Research Center (QRC) has been awarded a US$250,000 Julian Schwinger Foundation (JSF) Grant for his 'Rydberg Atomtronics' project. The project involves experimental sampling managed by Prof. Oliver Morsch’s group in Pisa and will run in collaboration with the University of Catania and the University of Pisa. The grant will facilitate the development of quantum circuits using Rydberg excitations for fast quantum devices and quantum computing. Why it matters: This funding and collaboration strengthens the UAE's position in quantum computing research and fosters international partnerships in advanced technology.
