Archer Materials uses CMOS technology to detect quantum information
Archer Materials 表示，使用标准半导体制造技术制造的芯片技术可以在“实际条件”下检测量子信息。
Technology company Archer Materials (ASX: AXE) has announced a “step-change” advance in the development of its 12CQ chip as it has been able to detect quantum information in the qubit material at room temperature.
The company, which develops advanced semiconductor devices including processor chips relevant to quantum computing, said it used complementary metal-oxide-semiconductor (CMOS) technology for the first time to detect the information.
CMOS is the predominant technology used in designing chips in the semiconductor industry and is broadly used today to form integrated circuits in numerous and varied applications including electronic devices such as processors, memory, and sensors.
Achievement builds on earlier technological progress
Archer chief executive officer Dr Mohammad Choucair said the significance of this development “cannot be understated” and represents a “step-change technological achievement” in advancing the company’s 12CQ quantum chip development.
“A key advantage of the new CMOS chip is that the componentry is made using standard and commercially available semiconductor fabrication technology,” he said.
“This achievement builds on the considerable progress Archer has made this year in the design and development of the 12CQ chip, which all link to the future operation of the technology,” Dr Choucair added.
Archer had previously shown that quantum information in the 12CQ qubit material could be detected using high electron mobility transistor (HEMT) technology, which is also widely used in integrated circuits such as those in mobile phones.
Quantum information in the 12CQ qubit material
According to Archer, the quantum information in the 12CQ qubit material is in the form of electron ‘spin’ states and significant innovation is required to, firstly, design and develop on-chip devices that can detect the electron spin states under practical conditions, and secondly, have these devices manufactured using standard industrial semiconductor processes.
The company has now confirmed that CMOS technology can detect the quantum spin states in the as-prepared 12CQ qubit material in a controlled atmosphere at room temperature.
The states were found to be “sufficiently well preserved when operating in the on-chip environment”, it reported.
Archer believes it is important to demonstrate the functional incorporation of the 12CQ qubit material with CMOS devices given the expectation that the use of CMOS technology in the semiconductor industry will continue in the long term.
