By building and controlling "qubits", one can manipulate highly entangled states to arrive at solutions for certain problems with exponential speedup over best-known classical alternatives. Qubits are notoriously hard to control and isolate, however, which leads to an assortment of errors that can quickly corrupt computation. </span></div><span class="" style="font-size: 15px;"><br class="">In this talk I will show evidence that a hardware/software co-design approach can push the boundary of feasible quantum computation. In other words, by gaining insight into the types of noise that arise in hardware (using characterization or other means), and also the structure of the problem, we can tailor a software stack and architecture that greatly relieve the hardware from stringent accuracy requirements. I will illustrate this through examples from quantum phase estimation, quantum volume, and quantum chemistry.<br class=""><br class="">I will conclude with some remarks about language support for enabling better programmability and optimization on near-term quantum computers. I will introduce our recent work on the OpenQASM dialect that acts as a multi-level circuit representation and IR. I will show examples of the types of programs that can be written using the new version of this language, including how gradual levels of hardware specificity can be introduced into the code to capture design intent but keep code portable. I will also contemplate the usefulness of IRs beyond QASM-style circuits.</span></div><div class=""><span class="" style="font-size: 15px;"><br class=""></span><div class=""><font class=""><span class=""><div class="" style="font-variant-ligatures: normal; background-color: rgb(255, 255, 255);"><div class=""><font class="" style="font-size: 15px;"><b class="" style="color: rgb(33, 33, 33);">Bio: </b></font><span class="" style="font-size: 15px;">Ali Javadi-Abhari is a Research Staff Member and Manager of the Quantum Compiler group at IBM.
