A cloud provider may host access but not necessarily own the hardware.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Can quantum hardware be fully cloud-hosted?<\/h3>\n\n\n\n<p>Many vendors offer cloud-hosted access, but some experiments need on-prem hardware for latency or IP reasons.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How often should calibration run?<\/h3>\n\n\n\n<p>Varies \/ depends on device and environment; common cadences are hourly to daily based on drift.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Are SLAs common for quantum hardware?<\/h3>\n\n\n\n<p>Yes for commercial offerings, but specifics vary widely and often include calibration windows.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How do you handle firmware rollbacks safely?<\/h3>\n\n\n\n<p>Use canaries, automated rollback criteria, and pre-deployment test suites.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What telemetry is most critical?<\/h3>\n\n\n\n<p>Device availability, gate\/readout fidelity, calibration success, and control-plane latency.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How do you reduce on-call noise?<\/h3>\n\n\n\n<p>Aggregate alerts, suppress routine calibration notifications, and route alerts appropriately.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Is quantum hardware secure by default?<\/h3>\n\n\n\n<p>No; physical access controls, firmware signing, and network segmentation are necessary.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What is a common cause of fidelity degradation?<\/h3>\n\n\n\n<p>Calibration drift and environmental interference are frequent causes.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How do you integrate vendor telemetry into internal SRE workflows?<\/h3>\n\n\n\n<p>Map vendor metrics to internal SLIs and ingest via secure APIs or exporters.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What disaster recovery applies to quantum hardware?<\/h3>\n\n\n\n<p>Spare parts, redundant control paths, and failover scheduling are common strategies.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Can you run chaos experiments on live hardware?<\/h3>\n\n\n\n<p>Yes but with controlled scope, backups, and clear abort procedures.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How do you measure job correctness beyond success rate?<\/h3>\n\n\n\n<p>Use benchmark circuits and compare against baseline noise models.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What is the role of simulation in hardware validation?<\/h3>\n\n\n\n<p>Simulators help validate control pipelines and test workflows before hardware runs.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How costly is telemetry retention?<\/h3>\n\n\n\n<p>High-resolution telemetry can be costly; use downsampling and tiered retention.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">When should you build your own hardware versus partnering?<\/h3>\n\n\n\n<p>If you need full control, unique qubit tech, or own IP; otherwise partner for speed.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What is quantum volume and why does it matter?<\/h3>\n\n\n\n<p>A composite metric of device capability; useful for comparisons but not sole indicator.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How do you prioritize feature work between hardware and software?<\/h3>\n\n\n\n<p>Use customer impact, SLOs, and error budgets to prioritize.<\/p>\n\n\n\n<hr class=\"wp-block-separator\" \/>\n\n\n\n<h2 class=\"wp-block-heading\">Conclusion<\/h2>\n\n\n\n<p>Quantum hardware companies bridge fundamental physics and production engineering, providing the physical systems and control stacks necessary to run quantum workloads.
