Direct experimental detection of anyonic exchange statistics in fractional quantum Hall systems by braiding the excitations and measuring the wave-function phase is an enormous challenge. Here, we use a small, noisy quantum computer to emulate direct braiding within the framework of a simplified model applicable to a thin cylinder geometry and measure the topological phase. Our algorithm first prepares the ground state with two quasiholes. It then applies a unitary operation controlled by an ancilla, corresponding to a sequence of adiabatic evolutions that takes one quasihole around the other. We finally extract the phase of the wave function from measuring the ancilla with a compound error mitigation strategy. Our results open a new avenue for studying braiding statistics in fractional Hall states.
Performing quantum logic gates on multiple quantum information bits (qubits) represented by photons is challenging. Here, we invent a resource-efficient way to deterministically perform a gate that underlies the quantum Fourier transform, one of the most versatile quantum algorithms.
Science students are taught that science is a collection of facts and equations when in fact, science is a journey full of false starts, dead ends, and creative detours undertaken by scientists to uncover the truth of reality. A science student seeking to become a scientist must often regress back to a state of childlike wonder and curiosity to prepare for such a journey. We seek to spark this change with hundreds of Quick Takes and Inquiries into specifically chemistry and physics at the introductory level.
While the established infrastructure of academia promotes ventures into unknown intellectual territory, translating technologies from the enclaves of esoteric journals to the lives of everyone remains a challenge. Patents play a crucial role in the world beyond the university setting by disseminating academic work to those who can use it while financially protecting them. Here, we discuss why an academic scientist would or would not patent, review the basics of patents relevant to a university setting, walk through the steps of filing patents at a university, and provide a more holistic analysis of the role of patents in various industries.
Extracellular matrix, or what's leftover after all the cells from tissues and organs are stripped away, has been shown to promote tissue regeneration. Here, we study extracellular matrix from different tissue types, ranging from intestinal to liver to brain, and show that some stimulate tissue regenerative pathways, while others stimulate inflammatory pathways that are known to hinder tissue regeneration.
