Cloud Quantum Computing At The Edge

Quantum computing has long been touted as a revolutionary technology, but its accessibility remains limited due to the need for expensive laboratory equipment and specialized expertise. Researchers are now exploring innovative strategies to democratize quantum computing, including mobile edge quantum computing that leverages small-scale, non-error-corrected devices connected to error-corrected servers.

This approach promises to create a quantum cloud compatible with different encoding protocols, enabling the connection and clustering of processors in a plug-and-play manner. However, significant challenges remain, particularly the need for error correction as qubit numbers increase. Researchers are exploring various techniques to mitigate these issues, including logical qubit encoding and complex optimization methods.

The development of quantum terminals is also crucial, providing a universal photonic interface for clustering processors and connecting them with quantum memories and clouds. These terminals have significant implications for the field, enabling the creation of complex quantum algorithms that can be executed on large-scale fault-tolerant quantum processors.

While more research is needed to overcome current limitations, this work holds great promise for bringing the benefits of quantum computing to a wider audience. As researchers continue to push the boundaries of what’s possible, it’s clear that democratizing quantum computing will require innovative solutions and a collaborative effort from experts across various disciplines.

The concept of bringing quantum computing capacities to personal edge devices has been gaining traction in recent years. However, the challenge lies in creating simple, non-error-corrected personal devices that can offload computational tasks to scalable quantum computers via edge servers with cryogenic components and fault-tolerant schemes. This approach would require network elements to deploy different encoding protocols.

Mohammadsadegh Khazali’s proposal for a universal terminal for cloud quantum computing is an attempt to address this challenge. The idea is to create devices that can accommodate the atomic lattice processor inside a cavity, providing an entangling mechanism through Rydberg cavity-QED technology. This technology allows for the entanglement of logical qubits across different encoding protocols.

The proposed scheme involves using an auxiliary atom responsible for photon emission to sense the logical qubit state via long-range Rydberg interaction. The state of the logical qubit determines the interaction-induced level shift at the central atom, which in turn derives the system over distinguished eigenstates featuring photon emission at early or late times controlled by quantum interference.

Applying an entanglement-swapping gate on two emitted photons would make the far-separated logical qubits entangled regardless of their encoding protocols. This proposed scheme provides a universal photonic interface for clustering processors and connecting them with quantum memories and quantum clouds compatible with different encoding formats.

Complex quantum algorithms demand large-scale, fault-tolerant quantum processors. However, current noisy devices encounter error-scaling issues as qubit numbers increase, hindering the execution of intricate tasks. Error correction becomes imperative achieved through logical qubit encoding across multiple physical qubits protected by error-correction codes.

Quantum operations at the logical level necessitate an abundance of operations at the physical qubit level, entailing costly techniques like complex optimization, magic state distillation, transversal gates, and lattice surgery. Consequently, the computational power and capacity requirements for quantum processors skyrocket. Moreover, accessibility to fault-tolerant quantum computation on personal devices remains constrained by the need for laboratory equipment such as laser cooling and cryogenic environments.

To democratize the quantum advantage, an optimized cost-benefit strategy entails the deployment of small-scale, non-error-corrected mobile devices that delegate computational tasks to error-corrected servers. Consequently, elements within the quantum cloud necessitate different encoding protocols. A plug-and-play approach for clustering and connecting these devices demands universal terminals compatible with all encoding schemes.

This paper introduces a novel scheme designed to entangle a single photonic qubit with a logical qubit encoded across 4 atoms. The proposed scheme provides a universal photonic interface for clustering processors and connecting them with quantum memories and quantum clouds compatible with different encoding formats.

The deployment of small-scale, non-error-corrected mobile devices requires the use of different encoding protocols within the quantum cloud. This approach necessitates the development of universal terminals that can accommodate various encoding schemes.
