Great new section in the Qiskit textbook by Almudena Carrera focusing on solving linear systems of equations using the HHL algorithm! It has examples of the algorithm for a few qubits, and runs HHL using Qiskit Aqua on both simulators and real hardware. qiskit.org/textbook/ch-ap…

If you enjoyed last week’s #IBMQuantumChallenge, you can read more about quantum key distribution (exercise 3) here: qiskit.org/textbook/ch-al…

Dear #quantumtwitter -- you've mostly been quiet these past few days, and the silence is deafening. Please reach out to your black colleagues and ask how they're doing tomorrow as the work week starts up again.
