Cisco Unveils Quantum Networking Chip, Opens New Lab to Advance Future of Quantum Connectivity

/in /tarafından

Cisco Systems revealed a prototype quantum networking chip on Tuesday and announced the opening of a new quantum research lab in Santa Monica, California, marking the company’s formal entry into the fast-evolving field of quantum computing.

Unlike competitors focused on building standalone quantum computers with increasingly more qubits, Cisco’s efforts aim to link quantum systems together, enabling larger-scale quantum computing through networking. The chip, developed in partnership with researchers from UC Santa Barbara, facilitates quantum entanglement between pairs of photons, which can then be transmitted to separate quantum computers—allowing them to share entangled states and communicate instantaneously over long distances.

“There are a whole bunch of use cases,” said Vijoy Pandey, SVP of Cisco’s Outshift innovation incubator. These include high-precision time synchronization for financial trading, global scientific coordination, and even space research applications like meteorite detection.

Quantum entanglement—the same phenomenon Albert Einstein called “spooky action at a distance”—is at the heart of Cisco’s chip design. For now, the technology remains in the prototype phase with no immediate revenue timeline, but Cisco views it as the first building block toward a scalable quantum internet.

Cisco joins a growing list of major tech firms—including Google, Microsoft, Amazon, and Nvidia—racing to lead in quantum innovation. While others build the processors, Cisco is positioning itself as the quantum network infrastructure provider.

Juniper Networks Denies Allegations in DOJ Lawsuit to Block $14 Billion Merger with HPE

/in /tarafından

Juniper Networks has formally denied the U.S. Department of Justice’s (DOJ) allegations regarding the $14 billion acquisition of the company by Hewlett Packard Enterprise (HPE). In a recent court filing, Juniper stated that the DOJ’s complaint, which seeks to block the all-cash takeover, misrepresents the competitive landscape for wireless network solutions.

DOJ’s Allegations:

The DOJ filed a lawsuit last month, arguing that the merger would lead to reduced competition in the networking equipment market, resulting in Cisco Systems (CSCO.O) and HPE controlling over 70% of the U.S. market. The department claims this dominance could harm consumers and stifle innovation in the industry.

Juniper’s Defense:

In its filing to a federal court in California, Juniper Networks disagreed with the DOJ’s assessment. The company argued that there are at least eight other competitors in the U.S. market offering wireless networking solutions, reducing the potential for anti-competitive behavior. Juniper further stated that Cisco has maintained more than 50% of the market share for over a decade, while the combined share of HPE and Juniper has been less than 25% in the last three years, not approaching a level that would trigger antitrust concerns.

Market Impact:

Juniper contended that the merger would enhance competition, particularly in challenging Cisco’s market dominance. The company emphasized that the combination of HPE and Juniper would not create a monopoly but rather foster greater competition in the sector.

Legal and Political Context:

This lawsuit marks the DOJ’s first significant antitrust action since President Donald Trump’s second term in office. The case is closely watched as it could set a precedent for future mergers and acquisitions in the tech industry.

Chinese Hack of U.S. Telecoms Compromised More Firms, WSJ Reports

/in /tarafından

A Chinese cyberattack has compromised more U.S. telecom companies than previously reported, including Charter Communications (CHTR.O), Consolidated Communications (CCII.UL), and Windstream, according to a Wall Street Journal report. Hackers exploited unpatched devices from security vendor Fortinet and compromised routers from Cisco Systems (CSCO.O), infiltrating networks of major firms such as AT&T (T.N), Verizon (VZ.N), Lumen Technologies (LUMN.N), and T-Mobile (TMUS.O).

The attack, linked to the Chinese-backed Salt Typhoon cyberespionage operation, raised concerns about the scale of the breach and the vulnerability of critical infrastructure. U.S. national security adviser Jake Sullivan warned telecom and tech executives that Chinese hackers could potentially disrupt U.S. ports, power grids, and other infrastructure. The affected companies have since secured their networks and worked with law enforcement and government officials to mitigate further damage. However, the hack is a reminder of the growing risks of state-sponsored cyberattacks.
