I’ll return to this below in more detail.
For now, all we need to know is that it will apply a quantum state that helps us randomize the roll of the dice. If you aren’t familiar with the Hadamard gate, don’t worry.
The QVM is great for testing and development, and towards the end of this post, I’ll show you how to replace the QVM with an API connection to the actual quantum computer itself. QVMConnection enables us to connect to a quantum virtual machine (QVM), a powerful 26-qubit simulator of a quantum computer.
Quantum programs are written in Forest using the Program object, which accepts the main logic of our application.Now that you’ve installed pyQuil, open up your code editor, or spin up a Jupyter notebook, and create a new file named quantum_dice.py.Īt the top of the file, we’ll import the following: from pyquil.quil import Program from pyquil.api import QVMConnection from pyquil.gates import H from functools import reduce qvm = QVMConnection() Once you have the right version of Python, you’ll need to install pyQuil: conda install -c rigetti pyquilĪlternatively, you can also pip install pyquil, although some users have experienced issues with this method, so we recommend using conda. If you don’t already have Python, or if you have an older 2.x version, I recommend downloading and installing the Anaconda Python distribution here. While you wait, check that you have Python v3.x installed (you can run python -version in your terminal to check which version you have). Once signed up, you’ll receive your API key within a few minutes via email. In this post, I’ll introduce you to the basics of quantum computing, demonstrate why they’re useful, and show you how easy it is to start building quantum programs.įirst, you’ll need to sign up for a free API key for Forest here. Near-term applications are being developed to solve some of the world’s most complex problems-such as simulating molecules that lead to the discovery of new materials and pharmaceuticals, designing catalysts to help build next generation battery technologies, and solving complex optimization problems for achieving new advancements in machine learning and artificial intelligence. Today, there’s already thousands of developers, researchers, and organizations using the Forest SDK, with over 60M+ jobs run to date. Some context: I’m a product manager at Rigetti, and we’re building quantum computers that anyone can access over the cloud.
