QUANTUM COMPUTING @ MPHASIS

 

Quantum computing is breaking the nature’s code to deliver the promise of unprecedented growth in computational power. It enables building systems which include richer data handling and processing elements, as compared to the ones currently being used by traditional computing systems. Quantum computing reduces the training time for algorithms significantly as well as efficiently finds optimal parameters through quantum superposition and entanglement, leading to quantum parallelism. It improves predictions through Bloch sphere representation, reducing the search space for the model parameters. It also helps arrive at better solutions that work even for non-convex optimization problems.

 

Mphasis is at the forefront in using quantum computers for machine learning, optimization and simulation problems. As a pioneer in delivering AI/ML solutions, we foresee quantum computing as a major driver in solving our clients’ business problems.

 

MPHASIS EON (ENERGY OPTIMIZED NETWORK)
QUANTUM COMPUTING FRAMEWORK

 

Mphasis EON (Energy Optimized Network) is a patent pending, classical-quantum hybrid network, consisting of energy optimization, quantum circuit and deep neural network layers. A quantum assisted, deep learning architecture is the recommended approach to solve ML problems. The deep learning part handles the data preprocessing step, while the quantum hardware performs the task of parameter search. The efficiency of quantum assisted, deep learning system is much higher than the efficiency of two systems, when used separately.

 

Quantum machine learning works on the principle of superposition and entanglement. Feature engineering and preprocessing the data to suit the quantum properties for learning, enhances the training performance of quantum circuits, resulting in better training accuracy. Energy Optimized Network (EON) constitutes of a deep neural network and feedback loop, dedicated to learning the incoming information and transforming the data into new feature space.

 

MPHASIS EON FRAMEWORK FOR
QUANTUM ASSISTED MACHINE LEARNING

 

Mphasis EON standardizes the classical data to bring all the values in a range of [0,1], to reduce the big number effect on machine learning. After standardization, input data is manipulated to prepare enhanced feature space that can better represent classical data on quantum systems for predictive tasks. The transformed feature space is mapped onto quantum systems using quantum state preparation such as angle embedding, amplitude embedding etc. Quantum circuits perform a defined series of operations on quantum data and measure the system information using the measurement function. The output from measurement functions becomes the input to deep neural network layers. The resultant cost function resides on the classical machine. The measured error is reduced by back propagation and different gradient descent methods.

 

Mphasis EON follows an iterative process to select the best suited feature space transformation, by reducing the overall energy of the network and capturing as much information spread as possible. For classical data to input on quantum computational systems, data encoding is a necessary step, and the strategy of how to represent classical data on quantum systems influence the quantum circuit design and its efficiency. A better expression of data on quantum systems, for a given machine learning task, leads to low information loss, faster convergence and better solution, due to quantum efficient optimization as compared to their classical counter parts. Mphasis EON achieves the optimal information representation for quantum using feature space transformation and batch sampling.

 

Strategic batch sampling methods are adopted to feed the quantum circuit such that each batch incorporates the overall pattern of information spread. This continuous and adaptive strategy to enhance feature space preparation for quantum predictive tasks make it more performance centric, resulting in faster convergence with fewer qubit requirements.

Quantum Consulting, Assessment & Workshops

Our Quantum Assessment, Consulting and Workshop will help clients get started with their Quantum Computing journey. This engagement enables clients to plan for the future and identify the relevant business problems which could be candidates for solving using a Quantum approach. Assessments are a fast way of identifying if Quantum is the relevant technology to leverage for solving a business problem and we leverage a qualitative and quantitative questionnaire-based approach for assessing the same. Workshops are usually week-long engagements with 4 Quantum Computing experts working closely with the client stakeholders to understand the system and data, and outcome of this exercise is a prioritized set of use cases along with recommended Quantum infrastructure to solve the problems. Quantum Consulting is a 3 weeks engagement, where we help clients evaluate their software and hardware requirements, fine tune identified use cases and set up the environment for development of the Quantum Algorithms. We provide expertise in almost all the quantum platforms available for example, annealing based systems like D-Wave, and circuit-based systems like CIRQ, Rigetti etc.

 

Quantum Algorithm Development and Implementation

Algorithms Development and Implementation is a 2-3 months long engagement, where we bring our IP as well as customizations to solve the specific client problems. Our services are powered by our patent pending framework Energy Optimized Network (Mphasis EON). The framework overcomes the limitations of quantum computing systems not being able to work on varied input datasets. The framework consists of Quantum assisted Machine Learning, Quantum Circuit and Deep neural network layers. The input data is fed to Mphasis EON to prepare enhanced feature space that can better represent classical data on quantum systems for predictive tasks. Inputting Big data onto quantum systems is a challenging task and Mphasis EON simultaneously learns data patterns as well as performs quantum predictive tasks in an iterative mode, making quantum to handle big data effectively. Better training accuracy is achieved through better representation of information by feature space transformation thus, exploiting hidden patterns in data, resulting in better learning of complex patterns. Optimal information representation for Quantum is achieved using feature space transformation and batch sampling. Feature space preparation for Quantum predictive tasks are more performance centric, resulting in faster convergence with fewer qubit requirements.
