New photonic chip promises more robust quantum computers. By Centre for Quantum Computation & Communication Technology.
The Centre for Quantum Computation and Communication Technology (CQC2T) is a research center based in Australia that is focused on the development of silicon-based quantum computing technologies, including photonic chip and superconducting qubits. The center has a strong focus on the use of silicon as a material for quantum computing and has made significant contributions to the field of silicon-based photonics for quantum computing. This post covers their research work as of late 2021.
Quantum computing is a rapidly growing field that promises to revolutionize the way we process and analyze data. One of the key challenges in developing practical quantum computers is the fragility of the quantum bits, or qubits, that store and process the quantum information. Now, scientists have developed a new photonic chip that promises to be more robust and stable than previous technologies, bringing us closer to the goal of building practical, large-scale quantum computers.
A photonic chip is a tiny piece of silicon that contains a circuit of tiny optical structures that can manipulate and control light. These chips are used in a wide range of applications, from telecommunications to medicine. In the context of quantum computing, photonic chips can be used to create, control, and manipulate qubits, which are the building blocks of quantum computers.
The new photonic chip developed by scientists at the Australian National University (ANU) and the University of Sussex, is based on the use of silicon nitride, a material that is well-suited for photonics and has already been used in a wide range of applications. The chip is smaller than a grain of rice and contains a circuit of tiny optical structures that can manipulate and control the qubits.
One of the key advantages of this new chip is its robustness and stability. Traditional qubits are fragile and easily disturbed by external factors, such as temperature changes and electromagnetic interference. The new photonic chip, however, is much more robust and stable, and can withstand these disturbances without losing its quantum properties. This means that the qubits on the chip can be used for longer periods of time and can perform more complex algorithms.
The new photonic chip also has the potential to be scaled up to create large-scale quantum computers. Traditional qubits are limited by the number of qubits that can be placed on a chip, but the new photonic chip has the potential to hold many more qubits, making it possible to create large-scale quantum computers that can perform complex computations.
The Centre for Quantum Computation and Communication Technology (CQC2T) is a research center based in Australia that is focused on the development of quantum computing technology. The center was established in 2003 as a collaboration between the Australian National University (ANU) and the University of New South Wales (UNSW) with the goal of developing a new generation of quantum computing technologies.
CQC2T's research program is focused on the development of silicon-based quantum computing technologies, including photonic chip and superconducting qubits. The center has a strong focus on the use of silicon as a material for quantum computing, as it is a well-established material in the semiconductor industry and is therefore relatively easy to manufacture and integrate with existing technologies.
One of the main areas of research at CQC2T is the development of silicon-based photonic chip, which is a tiny piece of silicon that contains a circuit of tiny optical structures that can manipulate and control light. These chips are used in a wide range of applications, from telecommunications to medicine. In the context of quantum computing, photonic chips can be used to create, control, and manipulate qubits, which are the building blocks of quantum computers.
The center has made significant contributions to the field of silicon-based photonics for quantum computing, including the development of single-photon sources, integrated waveguides and resonators, and integrated photonic devices for quantum information processing.
