Layered Architecture for Quantum Computing

A Layered Architecture for Quantum Computing

Quantum computer architecture is a systematic approach to organizing the resources of a quantum computer. We approach this problem by proposing a layered framework which can be a template for any circuit-model quantum computer. In particular, this framework is modular and promotes fault-tolerance. Modularity is important for making manageable the unique engineering challenges associated with la...

A Layered Architecture for Quantum Computing Using Quantum Dots

We address the challenge of designing a quantum computer architecture with a layered framework that is modular and facilitates faulttolerance. The framework is flexible and could be used for analysis and comparison of differing quantum computer designs. Using this framework, we develop a complete, layered architecture for quantum computing with optically controlled quantum dots, showing how a m...

Programmable architecture for quantum computing

A programmable architecture called “quantum FPGA (field-programmable gate array)” (QFPGA) is presented for quantum computing, which is a hybrid model combining the advantages of the qubus system and the measurement-based quantum computation. There are two kinds of buses in QFPGA, the local bus and the global bus, which generate the cluster states and general multiqubit rotations around the z ax...

A Quantum von Neumann Architecture for Large-Scale Quantum Computing

As the size of quantum systems becomes bigger, more complicated hardware is required to control these systems. In order to reduce the complexity, I discuss the amount of parallelism required for a fault-tolerant quantum computer and what computation speed can be achieved in different architectures. To build a large-scale quantum computer, one can use architectural principles, from classical com...
