In his laboratory, Petta has trapped one or two electrons in microscopic corrals created by applying voltages to miniscule electrodes on a wafer of semiconductor.
Such a feat is an important step toward developing future types of quantum computers. Jason Petta, an assistant professor of physics, has found a way to alter the property of a lone electron without disturbing the trillions of electrons in its immediate surroundings.

The maser uses about one-billionth of the electric current needed to power a hair dryer and works at temperatures near absolute zero, so it is ideal for quantum computing, which requires cryogenic temperatures.Īnother advantage of the new maser is that the energy levels inside the dots can be fine-tuned to produce light at other frequencies, which cannot be done with other semiconductor lasers in which the frequency is fixed during manufacturing.Ĭollaborators Graduate students Yinyu Liu and Jiri Stehlik, and associate research scholar Christopher Eichler in the Department of Physics Jacob Taylor and Michael Gullans at the Joint Quantum Institute operated by the University of Maryland, the National Institute of Standards and Technology and the Laboratory for Physical Sciences.ĭevelopment status Patent protection is pending.

The quantum dots are made from single-crystal indium arsenide nanowires just 50 nanometers in diameter that enable the isolation of single electrons in each double quantum dot. Moreover, to build this quantum circuit, the team employed silicon and germanium materials heavily used in the. The photons then build into a coherent beam of microwave light. This exciting result from Jason Petta’s team is an important milestone towards this goal, as it demonstrates non-local interaction between two electron spins separated by more than 4 millimeters, mediated by a microwave photon. Professor of Physics Jason Petta and his team have built a device that is a step forward for silicon-based quantum computers, which will be able to solve. Unlike regular atoms, quantum dots can be connected to a battery that enables current to flow, causing the dots to emit photons that bounce off mirrors at each end of the cavity. The maser consists of two double quantum dots, which are small bits of semiconductor material that act like single atoms, placed at either ends of a microwave cavity. Its low power consumption, coupled with the ability to operate at extremely low temperatures, makes the maser useful for the creation of compact microwave amplifiers suitable for end-uses in chemical sensing and future quantum computing applications. Princeton Universitys Jason Petta has demonstrated a method that alters the properties of a lone electron without disturbing the trillions of electrons in its immediate surroundings. Jason founded Region of Plenty as an artisanal ceramic design brand in. His approach to ceramics is largely self-taught, enhanced by workshops on mould making and design with Angelo di Petta and Peter Pincus. What it does The quantum-dot microwave laser, or “maser,” produces coherent microwave-frequency light and is powered by the one-by-one flow of single electrons. Jason worked in a wide variety of media before centring his practice around clay, where he discovered a material rich for exploring the subjects of intimacy, relationships, and connection.
