General Description of the Research Project
The goals for this project are to develop a roadmap for the realization of scalable quantum computer architectures and methods for specifying and verifying these architectures using a systems approach. A key element of this research is the development of tools for quantum
computer system architecture design and performance modeling and applying these tools to analyze these architectures. The objectives for the summer project include:

C. For the purpose of the roadmap, identify the key elements (i.e., technologies, resources, etc.) needed to integrate the essential building blocks of quantum computer architectures into a system capable of large-scale computations and quantify their performance requirements based on specific application requirements.
Desired Skills: BS in Physical Science or EECS (minimum); Background in quantum theory, quantum information science and technology required; Familiarity with quantum circuit design, fault-tolerance applied to quantum circuit design, fault-tolerant quantum error correction and the stabilizer formalism; Familiarity with classical computer system architecture principles helpful but not required.

Quantum Computer Architectures and Components
The goals for this project are to develop scalable quantum computer architectures and methods for specifying and verifying these architectures using a systems approach. A key element of this research is the development of tools for quantum computer system architecture design and performance modeling and applying these tools to analyze
these architectures. For the summer project we consider the following objectives:
A. Identify the essential building blocks for quantum computer architectures (e.g., memory, processing units, interconnects).
B. Model the impact of component reliability on the overall reliability and
performance of the quantum computer architecture. For each building block element, quantify the dependence of the building block reliability on:
1. The failure probabilities of the lower level elements
2. Configuration of the building block quantum circuit
C. Develop efficient methods to compute block reliability for a given quantum circuitconfiguration and failure probabilities of the underlying components.
D. Quantify the number and type of physical operations required for each of the building blocks as a function of the number of physical qubits required for error correction. Generalize these calculations for families of error correcting codes in order to provide a straightforward way for designers to estimate the resources necessary given specific device technologies and building block designs.
Intern Tasks
A. Tool Development and Integration: We currently have a quantum computer scheduler and quantum computer reliability simulator.
1. Familiarize yourself with each tool and their inputs/outputs
2. Develop an integrated simulation tool that incorporates both the scheduler
and the reliability simulator.
3. Verify and validate this integrated tool
B. Apply the integrated tool developed under Task A to the analysis of the reliability of different quantum computer building blocks as a function of different error correcting codes, including large block codes. Examine the impact of different quantum circuit configurations and technologies for the underlying physical components on the building block reliability.
C. Develop initial release of these tools as Open Source.
D. Document the results of the tool development and analyses in a technical report.

BBN-1 - Quantum-enhanced LADAR systems
BBN Technologies is seeking an intern to assist in performing original theoretical research on quantum optical sensors. Modern day optical radars (LADARs) used for stand-off sensing applications use classical laser to interrogate a target region and use standard optical receivers such as coherent detection and photon counting receivers to capture the reflected light. Recent work has established that using an entangled source of light, which sends half of the entangled beam to interrogate the target region while retaining the other half at the transmitter, can potentially perform better target detection. Even though instances of such quantum benefits have been shown in various optical sensing scenarios, much work needs to be done to make such quantum sensors attractive for existing systems.
In this project, we aim to theoretically explore and characterize both entangled sources of light for transmitters and quantum optical receivers that harness the benefit of using entangled transmitters. These will be analyzed in the context of improved target detection and imaging applications. We will also explore issues related to implementation in relevant operational scenarios. The analysis will involve calculating the modulation transfer function, signal-to-noise, and resolution behavior of the end-to-end system. The project will develop and utilize the student's skills in quantum information theory, elementary quantum optics, and knowledge of linear systems and signal processing. The student will receive guidance from and collaboration with experts at BBN in each of these areas.
Requirements: Pursuing graduate work in quantum optics, quantum information and signal and image processing. Must be enrolled in the MIT iQuISE program.

BBN-2 - Quantum Networking
BBN Technologies is seeking an intern to assist in performing original theoretical research on quantum networks. A particularly interesting current challenge is to devise efficient methods of distributing entanglement across optical fiber-based quantum networks spanning large distances, up to continental (~1000 km) scale, which would greatly enhance applications such as distributed quantum computing and quantum key distribution. Such a feat will require quantum memories (which can be realized by, e.g. neutral or ionic atom ensembles) and quantum repeater stations, which are actively being developed and studied. They will be a limited and expensive resource in any quantum network, and it will be essential to design networks in a way that utilizes this resource in an efficient manner.
In this project, we aim to perform calculations of the achievable rates of entanglement distribution over complicated, realistic network architectures and develop techniques to optimize the design of such networks. Calculations will include physically motivated assumptions about quantum memory lifetimes and fidelities, and real-world considerations on the optical network design. The project will develop and utilize the student’s skills in quantum information theory, physical modeling of quantum mechanical systems, error correction, and network theory. It will involve guidance from and collaboration with experts at BBN in each of these areas.
Requirements: Pursuing graduate work in quantum information, communications and network engineering. Must be enrolled in the MIT iQuISE program.

NEC-3 - Unified control of discrete and continuous variables of light
This includes theory and experiment. Theoretical subjects would suit to early year students. In this course we first introduce to them the basis of quantum optics with squeezed states, homodyne detection, and photon counting, and then suggest theoretical simulations for some new protocols which will be near term experimental targets. Such simulations should take into account practical multimode structure and imperfections of squeezed sources and detectors, which would be very useful to learn practical skills for quantum information optics. On the other hand, experimental subjects require advanced techniques such as how to handle optical parametric oscillator, homodyne detector, and Si APD. Hence this opportunity is for higher grade students. We can offer an opprtunity to work with new digital control systems to drive a whole quantum optics circuit to generate and control superposition states of photon condensates. Five staff members are involved in this project.
