Practical Quantum Computing in the Era of Quantum Technology

Trapped ions are one of the leading candidates for realizing practically useful quantum computers. The technology has made tremendous amount of progress in the last half a decade, to an extent where practically meaningful applications can be run on these systems today. I will discuss application areas where quantum computers can make a practical contribution to the computational frontier, and the prospect for an era of quantum technology.

Quantum enhanced sensing: a broad overview
The fundamental limits of precision in estimating parameters embedded in light or matter are ultimately governed by the laws of quantum mechanics. I will discuss how tools from physics of optics and quantum information have led to the development of novel sensors---either new optical probes, preparation of entangled states of atomic sensors, or the design of non-classical optical receivers---which could lead to dramatic improvements in sensing performance. We will discuss applications ranging from nearer-term realizations such as a mechanical beam deflection sensor, RF photonic sensor enhanced with squeezed light, fiber optic gyroscopes, and super-resolution passive imaging for fluorescence imaging, to the really long-term goals such as high-resolution long baseline telescopes strung by distributed entanglement, to entanglement enhanced NV-center arrays for neuronal imaging.

Dr. Saikat Guha, UArizona HSIB 640

Quantum Possibilities for Biomedical Optical Imaging
Optical methods can offer rapid, high resolution, high sensitivity imaging for biomedical applications. Examples will be given about how quantum properties of light may help increase these desirable characteristics.

Dr. Jennifer Barton, UArizona HSIB 640

Towards Realizing Passive Optical Super-resolution via Quantum-inspired Modal Measurements
Traditionally, the resolving power of passive optical imaging systems was understood to be determined by the Rayleigh resolution limit. However, a rigorous analysis of the two-point resolution problem using Quantum information theory has demonstrated that the Rayleigh limit is not fundamental. In fact, we now know that the fundamental quantum optical resolution limit can be achieved by spatial mode de-multiplexing (SPADE) or mode sorting measurements. In this talk, I will discuss our work on pursuing a broader understanding and analysis of the quantum limits of passive optical imaging in the sub-Rayleigh domain (i.e., optical super-resolution) for more complex scenes (such as point source constellations, continuous line sources etc.), including use of adaptive modal measurements within a Bayesian inference framework.

What Quantum Networks Can Do for the Defense Industry
How is quantum technology projected to impact defense applications? With an emphasis on quantum networks which can link sensor and processor resources in powerful ways.  Raytheon Technologies is following these developments both from the standpoint of developing enabling technology for quantum networks and assessing its potential deployment in systems

  Quantum Error Correction is Essential for Scalability

Small quantum systems have been demonstrated across different quantum technologies and applications. The primary bottleneck to scalability is noise and decoherence, which can be systematically addressed only by quantum error correction (QEC). This talk will introduce the key idea of QEC and its application to quantum computing and networking.

Dr. Narayanan Rengaswamy, UArizona HSIB 640
  Challenges in Quantum Error Correction
In this talk, we show connections between quantum and classical error correction codes. We focus low-density parity check (LDPC) codes that are gaining significant attention for quantum applications. In classical applications, LDPC codes are adopted in numerous communications and data storage standards due to low hardware complexity decoding and excellent error correction capabilities, but quantum LDPC codes require novel and more sophisticated decoding algorithms to utilize their potential.

  Quantum photonics with integrated thin-film lithium niobate

I will introduce the recently developed thin-film lithium niobate platform for quantum photonic applications. The combination of the strong second-order nonlinearity in lithium niobate and the sub-wavelength optical confinement in integrated photonic structures provide the ideal platform for high-efficiency scalable quantum photonic systems. I will present our recent result on the first generation of squeezed vacuum with on-chip parametric down-conversion, as well as the development of a new phase matching technique to achieve the ultimate nonlinear efficiency in integrated lithium niobate waveguides.

Dr. Linran Fan, UArizona HSIB 640

Entanglement-enhanced optomechanical sensing
I'll describe a proof of principle experiment in which a pair of mechanical oscillators is probed with distributed squeezed light source, yielding a 25% improved sensitivity to a force field distributed over an effective aperture of 1 m.  I'll discuss the outlook for this experiment in relation to optomechanical inertial sensing in general and extreme applications such as optomechanical dark matter searches.

  Quantum-Enhanced Transmittance Sensing
We consider the problem of estimating unknown transmittance of a target bathed in thermal background light. We prove that quantum illumination using two-mode squeezed vacuum (TMSV) states asymptotically achieves minimal quantum Cramér-Rao bound (CRB) overall quantum states (not necessarily Gaussian) in the limit of low transmitted power. We characterize the optimal receiver structure for TMSV input, and show its advantage over other receivers using both analysis and Monte Carlo simulation.

Piezoelectric Quantum Microsystems Systems
Piezoelectricity is a property of a special class of materials that allows coupling between electric fields and strain. In this talk, I will discuss my research using piezoelectricity in specially designed microsystems to radically enhance the performance of and enable completely novel functionalities in two very different classes of microsystems. First, I will discuss how piezoelectrically actuated and optomechanically tuned photonic integrated circuits have enabled myriad novel and highly scalable systems for quantum computing. Then I will discuss how piezoelectricity can be used in novel ways to harness unique properties of quantum phononic devices.

  Dynamically Speeding Up Quantum Dynamics 

Strong interactions between the components of a quantum system are critical for leveraging quantum effects in quantum technologies. In this talk, I present a protocol to enhance such interactions through local controls, thereby speeding up the system’s evolution without knowing parameter details. I further show the experimental realization of the protocol in an ion trap system to demonstrate phase insensitive amplification of displacements and faster Rabi oscillations.

Dr. Christian Arenz, Arizona State University HSIB 531
  2D Material Quantum Dots
2D semiconductors host strongly bound excitons that can be controlled by external electric and magnetic fields. I will report on our progress developing deterministic and energy tunable quantum dots that show evidence of single exciton trapping. Single excitons can serve as single photon emitters and spin-photon interfaces.

High frequency superconducting quantum devices for computation, sensing and networking
Superconducting qubits are a leading technology for quantum computing and consist of nonlinear elements coupled to superconducting resonators typically read out around 4-8 GHz. The standard nonlinear component is the Josephson junction which is also a key component in superconducting mixers for THz Astronomy and in Superconducting Quantum Interference Devices (SQUIDs) which are used for magnetic field and current sensors. I will describe devices using nonlinear kinetic inductance as an alternative to Josephson junctions and give examples of new developments with these devices in the areas of high frequency qubits and quantum limited amplifiers which can operate at frequencies of 100s of GHz, enabling higher operating temperatures and facilitate networking between superconducting devices.

Trustworthy Federated Machine Learning: Noise to the rescue!
Federated Learning is an emerging paradigm which can enable multiple users to collaboratively leverage their private data to learn better data driven models. In this talk, we will give an overview of some of the privacy and robustness challenges in contemporary federated learning, and motivate the need for rigorous privacy accounting. I will then discuss some of our recent work on "Wireless" federated learning which shows that the inherent randomness, and the superposition nature of the wireless medium can be quite beneficial for both privacy and communication efficiency. I will also briefly discuss connections between privacy and robustness, and show how privacy preserving techniques could be useful in learning robust machine learning models.
