Robert S. Sutor

Robert S. Sutor has been a technical leader and executive in the IT industry for over 40 years. More than two decades of that were spent in IBM Research in Yorktown Heights, New York USA. During his time there, he worked on and led efforts in symbolic mathematical computation, mathematical programming languages, optimization, AI, blockchain, and quantum computing. He is the author of Dancing with Qubits: How quantum computing works and how it can change the world and Dancing with Python: Learn Python software development from scratch and get started with quantum computing, also with Packt. He is the published co-author of several research papers and the book Axiom: The Scientific Computation System with the late Richard D. Jenks. Sutor was an IBM executive on the software side of the business in areas including Java web application servers, emerging industry standards, software on Linux, mobile, and open source. He was the Vice President of Corporate Development and, later, Chief Quantum Advocate, at Infleqtion, a quantum computing and quantum sensing company based in Boulder, Colorado USA. He is currently an Adjunct Professor in the Department of Computer Science and Engineering at the University at Buffalo, New York, USA. He is a theoretical mathematician by training, has a Ph.D. from Princeton University, and an undergraduate degree from Harvard College. He started coding when he was 15 and has used most of the programming languages that have come along.

13.3 Quantum neural networks

Let’s recall some definitions regarding neural networks from my book Dancing with Python. 211, Section 15.8 neural network quantum$neural network node neuron

Figure 13.3 shows a neural network with three input nodes, four nodes in the hidden layer, and two output nodes. Another name for a node is a neuron. I’ve shown weights w in the network on the connections from the input nodes going to the hidden nodes, and from the hidden nodes to the output nodes. Note how the network sends the value of each node to every node in the next layer.

 Figure 13.3: Neural network with 3 inputs, 4 hidden nodes, and 2 outputs

We compute a value from the input values and weights for each node in the hidden layers. These are real numbers that we may restrict to the binary values 0 and 1. We also have an associated activation function for each node in the hidden layer, determining what value to send to...
