![]() The programs can trigger a shutdown of the Raspberry Pi by means of pressing and holding the SenseHat Joystick button straight down. The list of available models can be found at You may specify the processor noise model to use by calling the parameter -noise:Fake XXXXXX where "XXXXXX" represents the system. The default noise model used is FakeParis. This has the same effect as -local but builds a simulator based on a model of one of the physical IBM Quantum processors. You may specify a noisy local simulator by using the -noise parameter when starting. This disables all the network apis and can run with no internet connection to IBM Quantum. You may specify using a local qiskit-aer simulator by adding the -local parameter when starting. Specifying a backend other than the simulator will disable the looping component of this program and send the job only a single time to IBM Quantum. The 16 qubit display corresponds to a 16-qubit processorĪctual calculations are run using the quantum simulator backend for the quantum processor, to avoid overwhelming the physical processor in the IBM Quantum computing center, unless you specify a real backend using the -b parameter. Each of those rectangles touched by a squiggly line in the image on the left holds a qubit.) (It's called a bowtie because of the arrangement of the 5 qubits, and the particular ways they can interconnect via entanglement. The 5-qubit display formats output in a manner corresponding to the IBM 5-qubit "bowtie" quantum processor. The default is to load and run a 5-qubit random number-generating program. This version asseses the QASM program being loaded and selects either a 5-qubit or 16-qubit display accordingly. If the Pi is held on edge, the accelerometer is used to determine which edge is "up" and orients the qubit display accordingly (default is "up" equals towards the HDMI and USB power in ports). The 8x8 array on the SenseHat is used to display the results.Īlternatively, if no SenseHat is detected, it will launch and use the display on a SenseHat emulator session instead. ![]() This code is specifically designed to run on a Raspberry Pi 3 or later with the SenseHat installed. ![]() You may opt to send your quantum circuit to an actual quantum processor backend at IBM Quantum instead of the simulator Parses newer version numbers of qiskit properly Third Release: will fail over to SenseHat emulator if no SenseHat hardware is detected. (Only the orientation of the physical display will change according to the rotation of the Raspberry Pi) Fourth Release: -local option: can run on local Aer qasm_simulator backend instead of using IBM Quantum backends via network! -noise option runs local simulator with a noise model based on a real processor. If no physical hat is installed, this parameter is ignored and the emulator alone will be spun up. ![]() The -dual parameter will spin up a Sensehat emulator as well as use the display on a physical Sensehat, if one is detected. Your Raspberry Pi running code on the IBM Quantum quantum processors via Python 3 - with results displayed courtesy of the 8x8 LED array on a SenseHat (or SenseHat emulator)! Fifth Release: -dual option: adding Dual Display option. ![]()
