| -Quantum computing at Google has hit an exciting milestone with the achievement |
16 |
| -of [Quantum Supremacy](https://www.nature.com/articles/s41586-019-1666-5). |
17 |
| -In the wake of this demonstration, Google is now turning its attention to |
18 |
| -developing and implementing new algorithms to run on its Quantum Computer |
19 |
| -that have real world [applications](https://ai.googleblog.com/2019/10/quantum-supremacy-using-programmable.html). |
| 28 | +[TensorFlow Quantum](https://www.tensorflow.org/quantum) (TFQ) is a Python |
| 29 | +framework for hybrid quantum-classical machine learning focused on modeling |
| 30 | +quantum data. It enables quantum algorithms researchers and machine learning |
| 31 | +applications researchers to explore computing workflows that leverage Google’s |
| 32 | +quantum computing offerings – all from within the powerful |
| 33 | +[TensorFlow](https://tensorflow.org) ecosystem. |
| 34 | + |
| 35 | +* Integrates with [Cirq](https://github.com/quantumlib/Cirq) for writing |
| 36 | + quantum circuit definitions |
| 37 | +* Integrates with [qsim](https://github.com/quantumlib/qsim) for running |
| 38 | + quantum circuit simulations |
| 39 | +* Uses [Keras](https://keras.io) to provide high-level abstractions for |
| 40 | + quantum machine learning constructs |
| 41 | +* Provides an extensible system for automatic differentiation of quantum |
| 42 | + circuits |
| 43 | +* Offers many methods for computing gradients, including parameter shift and |
| 44 | + adjoint methods |
| 45 | +* Implements operations as C++ TensorFlow Ops, making them 1<sup>st</sup>-class |
| 46 | + citizens in the TF compute graph |
| 47 | +* Harnesses TensorFlow’s computational machinery to provide exceptional |
| 48 | + performance and scalability |

| -To provide users with the tools they need to program and simulate a quantum |
22 |
| -computer, Google is working on [Cirq](https://github.com/quantumlib/Cirq). Cirq |
23 |
| -is designed for quantum computing researchers who are interested in running and |
24 |
| -designing algorithms that leverage existing (imperfect) quantum computers. |
| 50 | +## Motivation |
25 | 51 |
|
26 | 52 | TensorFlow Quantum provides users with the tools they need to interleave quantum
|
27 | 53 | algorithms and logic designed in Cirq with the powerful and performant ML tools
|
28 |
| -from TensorFlow. With this connection we hope to unlock new and exciting paths |
29 |
| -for Quantum Computing research that would not have otherwise been possible. |
| 54 | +from TensorFlow. With this connection, we hope to unlock new and exciting paths |
| 55 | +for quantum computing research that would not have otherwise been possible. |
30 | 56 |
|
| 57 | +Thanks to its power and scalability, TensorFlow Quantum has already been |
| 58 | +instrumental in enabling ground-breaking research in QML. It empowers |
| 59 | +researchers to pursue questions whose answers can only be obtained through fast |
| 60 | +simulation of many millions of moderately-sized circuits. |
