Can Gravity be Quantized?
Since the advent of general relativity and quantum mechanics their unification has been the ultimate goal of theoretical physics. So far, however, the different approaches aimed at creating a theory of quantum gravity [1] have been unsuccessful. It seems a possible reason for this – that gravity might not be an interaction – has never been consistently examined. What also warrants such an exami...
متن کاملCan observed randomness be certified to be fully intrinsic?
In general, any observed random process includes two qualitatively different forms of randomness: apparent randomness, which results both from ignorance or lack of control of degrees of freedom in the system, and intrinsic randomness, which is not ascribable to any such cause. While classical systems only possess the first kind of randomness, quantum systems may exhibit some intrinsic randomnes...
متن کاملGravity can be neither classical nor quantized
I argue that it is possible for a theory to be neither quantized nor classical. We should therefore give up the assumption that the fundamental theory which describes gravity at shortest distances must either be quantized, or quantization must emerge from a fundamentally classical theory. To illustrate my point I will discuss an example for a theory that is neither classical nor quantized, and ...
متن کاملWhat Can Be Observed Locally? Round-Based Models for Quantum Distributed Computing
We consider the question of locality in distributed computing in the context of quantum information. Specifically, we focus on the round complexity of quantum distributed algorithms, with no bounds imposed on local computational power or on the bit size of messages. Linial’s LOCAL model of a distributed system is augmented through two types of quantum extensions: (1) initialization of the syste...
متن کاملCan spinor dipolar effects be observed in Bose-Einstein condensates?
Weak dipolar effects in atomic Bose-Einstein condensates (BECs) have recently been predicted to develop spin textures. However, observation of the spin textures requires us to decrease the magnetic field down to approximately 10 microG for spin-1 alkali BECs, so that they are not washed out by the Zeeman effect. We present a scheme to observe the magnetic dipole-dipole interaction in alkali BEC...
