In a remarkable stride forward in quantum computing technology, Chinese researchers at the Anhui Quantum Computing Engineering Research Center have announced the successful development of a high-performance anti-interference ruthenium oxide thermometer, as reported by Science and Technology Daily.
The groundbreaking thermometer, developed by QuantumCTek, boasts a starting temperature close to 6 millikelvin (mK), setting a new record within China and positioning the nation's ultra-low temperature measurement technology for superconducting quantum computing at the forefront of global advancements.
Vital Role of Ruthenium Oxide Thermometers
Ruthenium oxide thermometers play a crucial role in quantum computers by precisely measuring the temperature of the working environment within quantum chips.
According to technology expert Li Xu from QuantumCTek, "absolute zero" (around minus 273.15 degrees Celsius), also known as 0 Kelvin, represents the theoretical limit for achievable thermodynamic temperatures and is often referred to as the "lowest temperature in the universe."
Given the delicate nature of quantum states, quantum chips require operation at conditions near "absolute zero." Even the slightest temperature fluctuation can lead to the loss of quantum information. Thus, the use of ruthenium oxide thermometers for accurate monitoring of a quantum chip's operating temperature is essential for ensuring the stable operation of quantum computers, thereby enhancing the accuracy and reliability of calculations performed by these powerful machines, explained Li.
Significance for China's Quantum Computing Industry
Wang Zhehui, deputy director of the Anhui Quantum Information Engineering Technology Research Center, hailed the new thermometer as a major step towards solidifying China's self-sufficiency and control over the entire superconducting quantum computing industry chain.
This remarkable achievement marks a significant milestone in China's quantum computing journey, positioning the nation as a key player in advancing ultra-low temperature measurement technology for superconducting quantum computing on the global stage.
The development of the high-performance ruthenium oxide thermometer represents a critical advancement in the field of quantum computing and underscores China's commitment to driving innovation and self-reliance in cutting-edge technology.
