![]() Han and his team, with expertise in terahertz waves and electronic devices, joined forces with associate professor Dirk Englund and the Quantum Photonics Laboratory team, who provided quantum engineering expertise and joined in conducting the cryogenic experiments. I believe this could be a way to build largescale quantum systems,” says senior author Ruonan Han, an associate professor in the Department of Electrical Engineering and Computer Sciences (EECS) who leads the Terahertz Integrated Electronics Group. While this is still just a preliminary prototype and we have some room to improve, even at this point, we have shown low power consumption inside the fridge that is already better than metallic cables. “By having this reflection mode, you really save the power consumption inside the fridge and leave all those dirty jobs on the outside. The contactless communication system consumes up to 10 times less power than systems with metal cables. This reflection process also bounces back much of the power sent into the fridge, so the process generates only a minimal amount of heat. That chip also acts as a mirror, delivering data from the qubits on the terahertz waves it reflects to their source. Data encoded onto these waves can be received by the chip. Terahertz waves generated outside the refrigerator are beamed in through a glass window. To overcome this challenge, an interdisciplinary team of MIT researchers has developed a wireless communication system that enables a quantum computer to send and receive data to and from electronics outside the refrigerator using high-speed terahertz waves.Ī transceiver chip placed inside the fridge can receive and transmit data. Plus, more qubits require more cables, so the size of a quantum system is limited by how much heat the fridge can remove. ![]() The metal cables that connect these electronics bring heat into the refrigerator, which has to work even harder and draw extra power to keep the system cold. Heat causes errors in the qubits that are the building blocks of a quantum computer, so quantum systems are typically kept inside refrigerators that keep the temperature just above absolute zero (-459 degrees Fahrenheit).īut quantum computers need to communicate with electronics outside the refrigerator, in a room-temperature environment. ![]()
