40 years ago, quantum computing started. This week we have observed entanglement, improved the fidelity of 2 qubit gates and realized breakthroughs in room temperature qubits. If that is not enough: Arqit announces SPAC for quantum in space, AgnostiQ secures $2,4M CAD, Germany launches €2B quantum fund through 2025 to build their own computer, Qnami closes 4M CHF and Quantum Delta NL launches lightspeed to invest up to 13,6B. Bessemer to lead $100M round for Xanadu. Shenzhen R&D center to invest $108B over 5y including quantum.
There it goes. In one week almost more investment commited than the last quarter of last year. Now go and spend it wisely!

The Summary of the Week
Forty years ago, IBM researcher Charlie Bennett helped usher in the study of quantum mechanics’ impact on computing. IBM is still at it—and so is Bennett.

Quantum entanglement is the binding together of two particles or objects, even though they may be far apart – their respective properties are linked in a way that's not possible under the rules of classical physics.

Without any of its own hardware and most of its software heavy-lifting dedicated to front-end development, security, and broader AWS systems integration, the cloud giant could own the quantum computing user base. The reasons are simple, even if the business could get complicated.

If you thought quantum computing was a leap forward, get ready for the next step: the quantum internet, where quantum machines can be linked to each other to create powerful networks of superfast computing power. The vision is now even closer to becoming reality.

Last fall, we made the ambitious promise to demonstrate a 100x speedup of quantum workloads in our IBM Quantum roadmap for scaling quantum technology. Today, we're pleased to announce that we didn't just meet that goal; we beat it.

Paper: qRobot: A Quantum computing approach in mobile robot order picking and batching problem solver optimization
This article aims to bring quantum computing to robotics. A quantum algorithm is developed to minimize the distance travelled in warehouses and distribution centres where order picking is applied. For this, a proof of concept is proposed through a Raspberry Pi 4, generating a quantum combinatorial optimization algorithm that saves the distance travelled and the batch of orders to be made. In case of computational need, the robot will be able to parallelize part of the operations in hybrid computing (quantum + classical), accessing CPUs and QPUs distributed in a public or private cloud. Before this, we must develop a stable environment (ARM64) inside the robot (Raspberry) to run gradient operations and other quantum algorithms on IBMQ, Amazon Braket, D'wave and Pennylane locally or remotely. The proof of concept will run in such quantum environments above.
