Big cats: entanglement in 120 qubits and beyond

Entanglement is the quintessential quantum phenomenon and a key enabler of quantum algorithms. The ability to faithfully entangle many distinct particles is often used as a benchmark for the quality of hardware and control in a quantum computer. Greenberger-Horne-Zeilinger (GHZ) states, also known as Schrödinger cat states, are useful for this task. They are easy to verify, but difficult to prepare due to their high sensitivity to noise. In this Letter we report on the largest GHZ state prepared to date consisting of 120 superconducting qubits. We do this via a combination of optimized compilation, low-overhead error detection and temporary uncomputation. We use an automated compiler to maximize error-detection in state preparation circuits subject to arbitrary qubit connectivity constraints and variations in error rates. We measure a GHZ fidelity of 0.56(3) with a post-selection rate of 28%. We certify the fidelity of our GHZ states using multiple methods and show that they are all equivalent, albeit with different practical considerations.

Entanglement detection with classical deep neural networks

Abstract In this study, we introduce an autonomous method for addressing the detection and classification of quantum entanglement, a core element of quantum mechanics that has yet to be fully understood. We employ a multi-layer perceptron to effectively identify entanglement in both twoand three-qubit systems. Our technique yields impressive detection results, achieving nearly perfect accuracy for two-qubit systems and over 90% accuracy for three-qubit systems. Additionally, our approach successfully categorizes three-qubit entangled states into distinct groups with a success rate of up to 77%. These findings indicate the potential for our method to be applied to larger systems, paving the way for advancements in quantum information processing applications.

Classical interfaces for controlling cryogenic quantum computing technologies

Jack C. Brennan, João Barbosa, Chong Li +8 more

Quantum processors have the potential to revolutionize computing on a scale unseen since the development of semiconductor technology in the middle of the twentieth century. However, while there is now huge activity and investment in the field, there are a number of challenges that must be overcome before the technology can be fully realized. Of primary concern is the development of the classical technology required to interface with quantum systems, as we push toward a new era of high-performance, large-scale quantum computing. In this review, we briefly discuss some of the main challenges facing the development of universally useful quantum computers and the different architectures being investigated. We are primarily concerned with cryogenic quantum systems. These systems are among the most mature quantum computing architectures to date and are garnering a lot of both industrial and academic attention. We present and analyze the leading methods of interfacing with quantum processors, both now and for the next generation of larger, multi-qubit systems. Recent advancements in control cryoelectronics, both semiconducting and superconducting, are covered, while a view toward newer methods such as optical and wireless qubit interfaces is also presented.
