MIT and MITRE researchers have developed a groundbreaking quantum hardware platform called a "quantum-system-on-chip" (QSoC), which integrates thousands of qubits onto a single chip. This innovative platform uses diamond color centers, a type of artificial atom, to store and manage quantum information. The new system allows for precise control and scalability, crucial for advancing practical quantum computing. The researchers created a lock-and-release fabrication process to transfer diamond color center microchiplets onto a complementary metal-oxide semiconductor (CMOS) chip. This integration enables efficient control of a large array of qubits and supports extensive quantum communication networks. By tuning qubits across different frequencies, the QSoC architecture facilitates a novel entanglement multiplexing protocol, enhancing the potential for large-scale quantum computing. The development process involved complex nanofabrication techniques and custom-built cryo-optical metrology setups to measure performance and ensure stability. The team demonstrated the capability to tune over 4,000 qubits to the same frequency while maintaining their properties, marking a significant step toward scalable and practical quantum computers.

Researchers from Massachusetts Institute of Technology and MITRE demonstrated a scalable quantum-system-on-chip” (QSoC) architecture that enable easy control of qubits for efficient quantum computing To achieve this scale, researchers utilized diamond color center “microchiplets” that are compatible with modern semiconductor fabrication processes and have photonic interfaces to allow remote entanglement with other qubits. Each "microchiplets" can be controlled by separate spectral frequency using laser light. The researchers also designed and fabricated an array of 1,024 diamond nanoscale optical antennas that enable more efficient collection of the photons emitted by qubits. With further investment, the team expects to improve performance and have more control over the process #quantumcomputing #quantum Links: https://lnkd.in/g4XFDSny https://lnkd.in/gkvT84dx https://lnkd.in/gKjgZRRe

QuTech Researchers Achieve Breakthrough in Scalable Majorana Qubits for Quantum Computing Researchers at QuTech, a collaboration between TU Delft and TNO, have developed a method to create Majorana particles in a two-dimensional plane, a significant step towards producing a full Majorana qubit.

Toshiba Breakthrough Enables High-Fidelity Quantum Computing with Double-Transmon Coupler Researchers at Toshiba Corporation and RIKEN have made a breakthrough in quantum computing, developing a tunable coupler that can connect two superconducting qubits with unprecedented precision. This innovation enables the switching between executing and halting operations by turning the coupling between qubits "on" or "off". The team, led by Yasunobu Nakamura, has achieved a two-qubit gate fidelity of 98.4%, paving the way for the development of practical quantum computers. The coupler's performance can be tuned by adjusting an external magnetic flux, allowing for a wide range of coupling strengths from 6 kHz to 80 MHz. This technology has the potential to suppress crosstalk errors, which occur when control electromagnetic waves applied to one qubit affect another. Toshiba and RIKEN aim to further enhance the performance of their double-transmon coupler, targeting a two-qubit gate fidelity of 99.99% and scaling up the system for practical applications. #quantum #quantumcomputing #technology https://lnkd.in/dJcsbJHr
