The gold coloured base plate consists of a series of electrodes that are used to manipulate the electromagnetic field used to trap individual ions. This allows us to trap ions in separate regions of the machine to "load" ions (injecting qubits into the computer), measure the quantum state of ions and to entangle ions together (performing gate operations between two ions) https://images.squarespace-cdn.com/content/v1/57823850414fb585ab34488f/1485856357466-MG3OFQ89Q90Z9WX7EY4R/image-asset.png Blog - Blueprint for an ion-trap quantum computer X-junctions are fabricated together in a grid. Each X-junction contains a single ion qubit that can be initialised, interacted with its four neighbours to the north, east, south and west and measured. Repeating this structure allows for an arbitrarily large error-corrected quantum computer, capable of implementing any algorithm. https://images.squarespace-cdn.com/content/v1/57823850414fb585ab34488f/1485857668568-VM47ASCWIXUY5D4O153I/image-asset.png Blog - Blueprint for an ion-trap quantum computer We remove costly and difficult laser control for each ion qubit by a microwave pulse that is broadcast over the entire computer. Ions that we wish to address with the pulse are "tuned in" via manipulating the local magnetic field environment with control wires embedded under the surface of the ion trap. https://images.squarespace-cdn.com/content/v1/57823850414fb585ab34488f/1485856401418-8337ZG6ZEL5JQINBNVP7/image-asset.png Blog - Blueprint for an ion-trap quantum computer A module is a 36x36 array of X-junctions fabricated with necessary control electronics and mounted on a steel frame with piezo-actuators that allow for aligning modules together. Each module houses 36 qubits in our quantum computer. https://images.squarespace-cdn.com/content/v1/57823850414fb585ab34488f/1485856444711-DQFIOW06J1W2MCRI5GKP/image-asset.png Blog - Blueprint for an ion-trap quantum computer By connecting modules together we scan scale the computer to arbitrary size. Shown is several connected vacuum systems containing approximately 2.2 million X-junctions. This system would occupy the space of a mid-sized office and be able to run fully error corrected quantum algorithms. The entire computer is housed in a ultra-high vacuum, to eliminate any stray atoms that could collide with ion qubits. http://www.h-bar.com.au/blog/2016/10/30/quantum-technologies-and-the-launch-of-h-bar-quantum-consultants monthly 0.5 2016-11-01 http://www.h-bar.com.au/blog/category/Research monthly 0.5 http://www.h-bar.com.au/blog/category/commentary monthly 0.5 http://www.h-bar.com.au/blog/tag/%23architecture monthly 0.5 http://www.h-bar.com.au/blog/tag/%23newpartner monthly 0.5 http://www.h-bar.com.au/blog/tag/%23topological monthly 0.5 http://www.h-bar.com.au/blog/tag/%23quantum monthly 0.5 http://www.h-bar.com.au/blog/tag/%23iontraps monthly 0.5 http://www.h-bar.com.au/blog/tag/%23schwab monthly 0.5 http://www.h-bar.com.au/blog/tag/%23yeswequantum monthly 0.5 http://www.h-bar.com.au/blog/tag/%23australia monthly 0.5 http://www.h-bar.com.au/blog/tag/quantum monthly 0.5 http://www.h-bar.com.au/blog/tag/technology monthly 0.5 http://www.h-bar.com.au/blog/tag/%23arc monthly 0.5 http://www.h-bar.com.au/blog/tag/%23worldquantumforum monthly 0.5 http://www.h-bar.com.au/media daily 0.75 2024-11-03 https://images.squarespace-cdn.com/content/v1/57823850414fb585ab34488f/1475216419043-DTLHYD7C4C4QP01ES3WP/image-asset.jpeg Resources https://images.squarespace-cdn.com/content/v1/57823850414fb585ab34488f/1475216786795-5PKRH2BRELLAB8ZUOAK4/image-asset.png Resources https://images.squarespace-cdn.com/content/v1/57823850414fb585ab34488f/1730548113102-1OHFY5YL8RNO3GH5CXX3/Screenshot+2024-11-02+at+10.47.51%E2%80%AFpm.png Resources https://images.squarespace-cdn.com/content/v1/57823850414fb585ab34488f/1730548225867-7ZRCEKQP4J23CGBJV5Q9/Screenshot+2024-11-02+at+10.50.07%E2%80%AFpm.png Resources https://images.squarespace-cdn.com/content/v1/57823850414fb585ab34488f/1730548113104-5JKPDE6807N2IJ7MK974/Screenshot+2024-11-02+at+10.46.40%E2%80%AFpm.png Resources https://images.squarespace-cdn.com/content/v1/57823850414fb585ab34488f/1730548228171-3EMUMYVVFPCO5ZP9J22D/Screenshot+2024-11-02+at+10.49.34%E2%80%AFpm.png Resources https://images.squarespace-cdn.com/content/v1/57823850414fb585ab34488f/1730548251625-I7WSNMX2E8PJNUQ6QHTN/Screenshot+2024-11-02+at+10.50.39%E2%80%AFpm.png Resources https://images.squarespace-cdn.com/content/v1/57823850414fb585ab34488f/1730548564053-GBII97DUIFJVXI0EV2IU/Screenshot+2024-11-02+at+10.55.51%E2%80%AFpm.png Resources https://images.squarespace-cdn.com/content/v1/57823850414fb585ab34488f/1468297642557-O5Q4X2Z34C7TYB97VD11/chip2.2.20.jpg Resources https://images.squarespace-cdn.com/content/v1/57823850414fb585ab34488f/1730594374232-93EEFSDV9729PP61U8EV/Untitled+4.002.jpeg Resources https://images.squarespace-cdn.com/content/v1/57823850414fb585ab34488f/1730594392064-7ZBS72PCCS1OVALLSYL9/Untitled+4.002.jpeg Resources http://www.h-bar.com.au/work daily 1.0 2024-11-03 https://images.squarespace-cdn.com/content/v1/57823850414fb585ab34488f/1468160223515-ZOP8PNY1GZWASFA1WSWN/image-asset.jpeg h-bar https://images.squarespace-cdn.com/content/v1/57823850414fb585ab34488f/8178b83d-ed39-48c3-9e41-7fdc671f597a/Untitled+4.001.jpg h-bar - Make it stand out Whatever it is, the way you tell your story online can make all the difference. https://images.squarespace-cdn.com/content/v1/57823850414fb585ab34488f/1468160361449-MVJ0O6F7B6ZI62XZQ3V9/image-asset.jpeg h-bar https://images.squarespace-cdn.com/content/v1/57823850414fb585ab34488f/1468173033341-6C58ZHBWKQCC9BHO96F3/dot.jpg h-bar https://images.squarespace-cdn.com/content/v1/57823850414fb585ab34488f/6f524ad2-86e6-4f59-8e20-28e3a69d2711/Profile+Picture.jpg h-bar Prof. Simon J.
