Quantum Rounding
Rajiv Krishnakumar, William Zeng
We introduce new rounding methods to improve the accuracy of finite precision quantum arithmetic. These quantum rounding methods are applicable when multiple samples are being take…

A Threshold for Quantum Advantage in Derivative Pricing
Shouvanik Chakrabarti, Rajiv Krishnakumar, Guglielmo Mazzola +3
We give an upper bound on the resources required for valuable quantum advantage in pricing derivatives. To do so, we give the first complete resource estimates for useful quantum d…

Retrieval of cavity-generated atomic spin-squeezing after free-space release
Yunfan Wu, Rajiv Krishnakumar, Julián Martínez-Rincón +3
The compatibility of cavity-generated spin-squeezed atomic states with atom-interferometric sensors that require freely falling atoms is demonstrated. An ensemble of spin…
