Integrated optical approach to trapped ion quantum computation

Abstract

Recent experimental progress in quantum information processing with trapped ions have demonstrated most of the fundamental elements required to realize a scalable quantum computer. The next set of challenges lie in realization of a large number of qubits and the means to prepare, manipulate and measure them, leading to error-protected qubits and fault tolerant architectures. The integration of qubits necessarily require integrated optical approach as most of these operations involve interaction with photons. In this paper, we discuss integrated optics technologies and concrete optical designs needed for the physical realization of scalable quantum computer.

Towards fast and scalable trapped-ion quantum logic with integrated photonics

Trapped-ion qubits promise certain fundamental advantages for quantum information processing (QIP), owing to their indistinguishability and relatively high isolation from noisy environments. Though these qualities have allowed demonstrations of the necessary primitives for quantum computation, the complexity of the optical apparatus required is a major impediment to implementation at scales where quantum systems offer a clear advantage over classical computers. Here, we build on previous work with trap-integrated waveguide optics, describing designs and simulations for commercial foundry-fabricated ion trap chips with integrated Si3N4 waveguides and grating couplers to implement multi-qubit operations. We detail a design intended to address and implement quantum logic gates between 5 ions in a single register, and a configuration which utilizes the stable on-chip path lengths of waveguide devices to enact a novel fast entangling two-qubit gate. The devices and approaches presented here could form elements of a scalable architecture for trapped-ion QIP.

Scalable quantum information processing and the optical topological quantum computer

Simon J. Devitt

Optical quantum computation has represented one of the most successful testbed systems for quantum information processing. Along with ion-traps and nuclear magnetic resonance (NMR), experimentalists have demonstrated control of qubits, multi-gubit gates and small quantum algorithms. However, photonic based qubits suffer from a problematic lack of a large scale architecture for fault-tolerant computation which could conceivably be built in the near future. While optical systems are, in some regards, ideal for quantum computing due to their high mobility and low susceptibility to environmental decoherence, these same properties make the construction of compact, chip based architectures difficult. Here we discuss many of the important issues related to scalable fault-tolerant quantum computation and introduce a feasible architecture design for an optics based computer. We combine the recent development of topological cluster state computation with the photonic module, simple chip based devices which can be utilized to deterministically entangle photons. The integration of this operational unit with one of the most exciting computational models solves many of the existing problems with other optics based architectures and leads to a feasible large scale design which can continuously generate a 3D cluster state with a photonic module resource cost linear in the cross sectional size of the cluster.

In this paper, we define the importance of integrating atomic systems and photonic technologies, which revolutionize quantum computation. This concept merges the attributes of photonic processors like precision of atomic qubits, scalability, and speed while considering the current challenges like data transfer, error correction, coherence, etc. Taking the current advancement in quantum photonics like entangled photon pairs and optical quantum circuits, we can aim to create fault-tolerant and scalable quantum systems. This possibility shows the possible compatibility between atomic manipulation techniques like integrated waveguides, single-photon emitters, and trapped ions. We can find possible potential-filled applications in cryptography, optimization methods, and materials science while monitoring the challenges in hybrid architecture integration and quantum networking. This combined model plays a crucial step in making prototypes, which changes the shape of computation in coming technological advancement. We dive deep into the quantum computing and existing hybrid architectures, like fundamentals and challengers, photonics in quantum computing, and atom-photon interaction mechanisms.
